Getting Out the Vote in the Social Media Era: Are Digital Tools Changing
the Extent, Nature and Impact of Party Contacting in Elections?1
1 *The UK and U.S. dataset used for this project was funded by the UK Economic and Social Research Council (ESRC) through Research Grant RES-051-27-0299 and is archived at the UK Data Archive http://reshare.ukdataservice.ac.uk/850856/
Abstract:
This paper compares the spread and impact of new digital modes of voter mobilization with more traditional methods (phone, mail and in person canvassing) in recent national elections in the U.S. and UK. We develop hypotheses regarding the relative effects of online contacting and test them using election study data. Our findings show that while online contact by is generally less frequent than the offline form in both countries, this gap is particularly pronounced in the UK. U.S. campaigns also reach a much wider audience than their UK counterparts. In terms of impact, while offline forms remain most effective in mobilizing turnout, online messages are important for campaign participation, particularly among younger citizens when they are mediated through social networks.

Introduction:
The arrival of the internet and more recently social media has provided parties and candidates
with more personalized ways to engage voters. Research on the growth and effects of these
new types of voter contacting has increased over the past decade. Findings are mixed, with
some studies of email GOTV and registration campaigns showing no discernible effects
(Krueger, 2008; Nickerson, 2007; Stollwerk, 2006), while studies of text messaging have
been more positive (Dale & Strauss, 2007). A prominent Facebook experiment found small
but significant effects of seeing a GOTV message on a friend’s page (Bond et al, 2012).
This paper advances the debate on the effectiveness of online voter contact in three
main ways. First we develop a classificatory framework in which this new mode can be
understood in relation to existing offline modes. This allows us to better specify its
mobilizing effects. We then use election study data from the U.S. and UK, to measure the
extent of online contact in recent national elections. We then compare who received this
contact and its impact on voter turnout and campaign activities in each country. Do online
methods pack an extra mobilizing punch? Does this vary across countries and if so, why?
Literature Review
The study of voter contacting has a long history. Most of the work has focused on the U.S.
and looked at its impact on voter turnout. Studies have covered a range of elections and used
a variety of methods and data including self-reported contact in surveys and controlled
interventions using field experiments. The main conclusion drawn thus far has been that voter
contact, and particularly direct, face-to-face canvassing matters (Blydenburgh 1971, Beck
2002; Bergen et al. 2005; Cutright 1963, Gerber and Green 2000, 2008; Gosnell 1927, Katz
and Eldersveld 1961, Kramer 1971, Merriam and Gosnell 1924; Panagopoulos, and Francia
2009). Indeed some recent research has attributed the upturn in voter turnout in recent
elections to improvements in voter targeting due to the rich demographic, socioeconomic and
consumer or “big” data that campaigns can now access (Panagopoulos and Francia, 2009;
Wielhouwer, 1994).
Analyses beyond the U.S have confirmed the importance of voter contact.
Comparative studies by Beck (2002) and Magalhães (2007, 2010) using survey data from the
Comparative National Election Project (CNEP) covering up to fifiteen countries reported a
significant increase in voting after being contacted. Fieldhouse et al’s (2013) randomized
field experiments in the UK showed that contact matters for British voters. Interestingly
while the authors confirmed that personalized methods were most effective, they also found
3
that more remote methods such as direct mail had a stronger and cumulative effect compared
to the U.S.
The arrival of digital communication has provided new and more direct ways for
contacting voters and their mobilizing potential has been studied increasingly over the past
decade. Again studies have focused on the U.S. and looked primarily at the impact of one of
the most common forms of campaign contact - email. Conclusions are mixed. Early
randomized field experiments conducted in state and municipal elections between 2002 to
2005 reported no significant effects of email GOTV and registration campaigns (Stollwerk,
2006; Nickerson (2007). Subsequent work using survey data also found that receiving
unsolicited emails i.e. those which involved no prior sign-up, had no effect on levels of online
or offline political engagement (Krueger, 2010) . Malhotra et al. (2012), however, found that
emails from the local registrar had a small but significant effect on turnout, although those
from civic groups did not.
Studies of text messaging have yielded more positive results. Field experiments
conducted during the 2006 Congressional elections attributed a statistically significant three
percentage point increase in the likelihood of voting in response to a GOTV message (Dale
and Strauss, 2009). Malhoutra et al. (2011) again find a significant effect for messages sent
by local registrars reminding people to vote. Online advertising, however, is seen as
ineffective. Experimental studies of two legislative campaigns in 2012 found that exposure to
Facebook ads had no impact on voters’ name recognition or vote choice (Brockman and
Green, 2013).
The mixed findings about the impact of online contact are somewhat surprising given
the importance attributed to digital tools in Obama’s victory in 2008 (Kenski et al. 2010).
However most candidates would struggle to leverage the resources that Obama devoted to his
e-campaign. Furthermore the lack of a national register of email addresses and mobile phone
numbers means that campaigners are rarely, if ever, reaching an undecided voter through the
Web. The people contacted online are actually more likely to have already signed up to
receive campaign news. Finding mobilization and certainly conversion effects is, therefore,
highly unlikely. Finally even if campaigns could reach a large pool of undecided voters
through these channels their efforts may well be counter-productive. Mobile phones and
platforms like Facebook are highly personalized mediums of communication and unsolicited
messages are likely to be regarded as more intrusive than a ‘cold call’ to a landline or flyer
posted through the mailbox.
4
Given the barriers to parties’ reaching voters directly through online means, attention
has shifted to more indirect and mediated methods.. Evidence from a pioneering experiment
by Bond et al. (2012) conducted on 61 million Facebook users has showing that those who
received a reminder to vote message endorsed by a random selection of their friends were
significantly (0.4%) more likely to have voted than those who receive a neutral non-endorsed
message (vote validation was carried out on a sample). Although the increased likelihood was
small, based on the size of the user population of Facebook and likelihood of further
accidental exposure the authors estimated that over a quarter of million more votes were cast
than would otherwise have been the case. The idea that the impact of mobilizing messages’ is
increased when mediated through friends and family chimes with findings from the offline
contact literature. While the causal mechanism has not been extensively theorised it is clear
that social context and particularly discussion networks provide important cues for political
opinion formation and vote decisions (Lazarsfeld et al. 1948; Beck et al. 2002; Huckfeldt et.
al. 1995; Leighley, 1990; Magalhães 2007; Partheymüller and Schmitt-Beck, 2012; Popkin,
1991; Schmitt-Beck, 2008; Sniderman et al., 1991). Contexts of social interaction tend to be
characterized by a similarity of interests and mutual trust, increasing the likelihood that the
cues received are seen as credible and help provide a shortcut in political decision-making
(Huckfeldt and Sprague, 1995). This can be particularly consequential for individuals with
lower levels of political information and awareness (Zaller 1992; Beck et al. 2002). Partisan
messages mediated through online social networks are likely to operate in a similarly
mobilizing fashion.
Research Questions and Hypotheses
Drawing on the findings of the recent literature and prima facie reasoning we move to
formulate some expectations about the effects of online contact on voter behaviour. Given the
literature to date has shown that more personalized face to face contact is the ‘gold standard’
mode we start with the assumption that online methods are likely to be less effective than
offline, particularly door to door canvassing and telephone. This disadvantage is likely to be
compounded by the heavy reliance of online contact on prior sign-up and the extent to which
the channels it uses are seen as spaces for private interaction rather than public or commercial
communication. Countering these limitations, however, are the greater opportunities the
online environment offers to increase personalisation of messages through two-step
communication via social networks. While our dominant expectation, therefore, is that newer
types of online campaign contact will be less influential than traditional modes, we expect
5
this to apply particularly to contact direct from the parties. Contact that is mediated through
social networks is likely to be more extensive and equally as effective as that via offline
means. To set out these expectations more clearly we develop a categorisation of contact
based on these two axes of mode and source of contact. The resulting four-fold typology is
presented in Table 1.
Table 1 about here
The first axis centres on the mode of delivery – offline or online. For the former we include
four methods that have varying degrees of personalization but do not rely on digital channels.
For the online mode we include four of the main channels for digital communication - email,
SMS2, social network sites and Twitter. We then divide each mode according to whether the
source of contact is direct and comes via official channels or is indirect and is passed on
through friends or family.
Based on the prior discussion of the literature we advance four specific hypotheses
regarding the relative effects of the different types of voter contact:
H1 Direct offline contact is most likely to increase voter turnout.
H2 Direct online contact is least likely to increase voter turnout.
Our expectations for indirect contact are less specific although we would expect both types to
fall somewhere in between the two direct modes in regard to effectiveness. Given that a
confirmation of H1 and H2 leaves this as the logical or implicit outcome we restrict our
hypotheses to two at this point. 3
As well as examining the effects of contact on turnout we examine its impact on
campaign activity during the election. While the same caveats apply to online contact and the
greater difficulties it faces in reaching undecided voters compared with offline, given that
campaign activities have a cumulative quality and are likely to appeal to more highly engaged
supporters we expect this to reduce some of the disparity in the impact of online and offline
contact. This leads us to moderate the expectations of H1 and H2 as follows:
2 We acknowledge that sms or text messages form something of a hybrid in that they constitute a type of phone contact and thus could be seen as offline. However, to date they have been treated as part of the ‘new’ forms of communication by the studies referred to here. Also, typically now email and other types of web communication are accessed through one’s phone, making the distinction less clear. We treat them as online for purposes of this paper. 3 One might argue that the sheer scale and volume of online indirect contact would mean it would have a more pronounced effect than that occurring offline. However as with direct mobilization, face to face or more personalized efforts at persuasion by friends on behalf of a party may prove significantly more effective than an electronic prompts, countering this quantitative advantage.
6
H3 Direct offline contact and direct online contact will both significantly increase the
likelihood of engaging in campaign activities.
H4 Direct online contact will have a stronger effect on campaign activities than on
voting.
Before moving to test our hypotheses we reflect on how the comparative aspect of the
study may moderate our expectations. The cross-national research that exists indicates
significant variance in the incidence of contacting which appears to linked with the age of the
party system and electoral rules in place. (Karp and Banducci, 2007). Established
democracies where parties are well resourced and experienced see more voter contact. If
parties are also competing in single member districts (SMD) under majority/plurality rules
where cultivating the personal vote is important then the rates of contact increase further.
Also because turnout tends to be lower in plurality systems (Powell, 1986) mobilization
efforts have a greater potential to be effective. Given that the U.S. and the UK meet these
criteria we would expect both to exhibit healthy rates of contact, making them appropriate if
not ideal cases for analysis where contact constitutes a key independent variable.
Beyond these general similarities it appears that face to face methods are most
effective in both countries although direct mail appears to work better in the UK. Given that
we have merged these methods into a generic ‘offline’ mode however, we still expect H1 to
hold for both cases. Whether context would affect H2 is less clear based on existing research.
Online mobilization has achieved a higher profile in the U.S. than in the UK. and several
scholars have pointed out how the institutional environment of the former intensifies levels of
web campaigning (Anstead and Chadwick, 2008; Vaccari 2013). The candidate-centered
nature of campaigns, high cost and high frequency of elections in the U.S. creates a strong
incentive to use the more individualized and inexpensive medium of the web. Thus while one
would expect H2 to hold in the U.S. one might expect it to hold more strongly in the UK
given the greater restraint of parties toward online campaigning.
Conversely we would expect hypotheses 3 and 4 to gain stronger support in the U.S.
particularly in regard to presidential campaigns which are not only vastly longer than the
national campaign in the UK, but also much more costly. Candidates are responsible for
generating their own election resources unlike in the UK where they are typically supplied
through the party organization. This creates yet further pressure to exploit all available
options to reach voters over a sustained period of time.
Data and Methods
7
To test our hypotheses in the U.S. we use the 2012 American National Election Study
(ANES).4 The survey included indicators of all four forms of contact: online and offline
direct contact and offline and online indirect contact.5 In the UK we used two data sources
due to the fact that no single survey allowed us to test all four hypotheses. The first is a post-
election, face-to-face survey conducted by BMRB, a UK polling company.6 The survey
included indicators of three of the four forms of contact: online direct contact, offline direct
contact, and online indirect contact and our dependent variable voter turnout.7 This allowed
us to test H1 and H2. The second dataset is the post-election, cross-section, face-to-face
sample of the 2010 British Election Study (BES)8. This survey included detailed indicators of
online and offline direct contact9 and a measure of campaign participation but did not allow
us to split indirect contact into online and offline forms. It was used to test H3 and H410
4 Data collection for the ANES 2012 Time Series Study started in early September and ended in January, 2013. Pre-election interviews were conducted with study respondents during the two months prior to the 2012 elections and were followed by post-election interviews beginning November 7, 2012. The overall N was 2,056. Note that the contacting variables are drawn from the data gathered from running the CSES module IV battery.5 These indicators are derived from the following questions: during the campaign, did a party or candidate contact you in person or by any other means? (formal contact); during the campaign, did a friend, family member or other acquaintance try to persuade you to vote for a particular party or candidate? (informal contact); did they contact (try to persuade) you in person/face-to-face?; did they contact (try to persuade) you by mail?; did they contact (try to persuade) you by phone? (offline contact); Did they contact (try to persuade) you by text-message or SMS?; did they contact (try to persuade) you by email?; did they contact (try to persuade) you through a social network site or other web-based methods? (online).6 The fieldwork was conducted between the 20th and 26th of May, 2010. Control of quotas affecting likelihood of being at home (age and working status within sex) was applied following a one stage ACORN and region stratification. The data was weighted to ensure that demographic profiles matched those for all residents in Great Britain aged eighteen or over. The overall N was 1,960.7 The question wordings were: for direct contact – “In the course of the recent election did anyone from a political party, campaign or political organisation contact you to ask about how you were planning to vote through any of the following methods? Online or internet-based contact (i.e. through email or any internet/web-related technology); By telephone, mail or face to face; I have not been contacted; Don’t know or not sure”. For indirect online contact: “In the course of the recent election, did you receive any campaign-related political messages or content through the internet from a friend, a member of your family or someone at work? Yes; No; Don’t know or not sure”.8 The fieldwork was conducted between the 7th of May and the 5th of September 2010 by TNS-BMRB. The sampling followed a multi-stage stratified random design. Weighting was then used to ensure survey respondents are representative of residents in private households in Great Britain aged 18 years or older. The overall N was 3,075.9 These indicators are derived from the following battery: a) “Did any of the political parties contact you during the recent election campaign?”- b) “Which of the political parties contacted you during the recent election campaign?” - and c) “Please tell me all the ways that the party X contacted you during the recent election campaign: Telephone call; Leaflets or other material delivered to your home; Email or text message; Visit to your home; Contact in the street; Facebook, Twitter, YouTube”.10 This question did not specify through which method the contact took place (offline or online). The exact wording was: “Did anyone, for example, a friend, a member of your family, someone at work, or some other person try to convince you which party to vote for in the recent general election?”

Findings
We report first the rates of different types of contact in our two cases (Table 2) and then
profile the recipients (Table 3). As noted while we can provide information on all four types
of contact in the U.S. we are missing a specific measure of indirect offline contact in the UK.
Table 2 about here
As expected, Table 2 shows that overall rates of contact in both countries are robust. Offline
direct contact was particularly frequent during the British campaign with around half of the
electorate reporting contact from a party, campaign or political organisation by telephone,
mail or face-to-face canvassing. Contact from friends and family was lower with BES data
showing that 16% of the electorate had experienced this type of informal persuasion. The
BMRB data allow us to probe the mode of this contact further and indicate that a lot of it
occurred online, with 15% of voters receiving messages or campaign-related content from
people they knew. Online direct contact by parties by contrast was much lower with only 2%
of the electorate reporting this type of messaging. In the U.S. while rates of offline direct
contact were slightly lower than in the U.S. all other types of contact were substantially
higher. This was particularly the case for online direct contact which reached almost one in
five voters according to ANES results.
Table 3 presents the main demographics and political characteristics of those
contacted through online and offline methods in both countries. We use the BMRB data here
since it allowed us to more precisely specify the source and mode of offline contact than did
the BES.
Table 3 about here
The table reveals some differences among those receiving offline and online contact in both
countries although the differences are more pronounced in the UK, particularly with regard to
age. Online contactees in the UK are typically younger, more likely to be male, highly
educated and more interested in politics than those receiving offline contact. The greater
convergence in the profiles of online and offline contacting in the U.S. is interesting in that it
suggests the former is becoming a more mainstream strategy and that our expectation about
the moderating effects of context on our hypotheses is correct. U.S. parties do appear to be
more advanced and proficient than their UK counterparts in targeting a wider range of voters
9
through online methods and overcoming the self-selection biases associated with this
approach. More specifically this supports the idea that H2 (weaker effects for online contact)
will be more strongly supported in the UK.
Mobilization Effects
To test our hypotheses we examine the effects of different types of contact on turnout and
campaign participation in the U.S. and the UK using survey data gathered in recent national
elections. In doing so we recognize that analysing voting behaviour using survey data
presents challenges to an investigation of causal claims in general11 and more specifically
with regard to questions of mobilization due to the perennial problem of over-reporting . On
this latter point our data clearly form no exception. Seventy five percent of the BMRB sample
report having voted in the general election (77% in the BES sample) while actual turnout in
2010 was 65 percent.12 In the United States the problem is slightly worse with ANES self-
reported turnout standing at 71% compared to the actual rate of 58%13. The problem is further
compounded by the fact that our key independent variable (campaign contact) is also self-
reported. In the case that unobservable errors in both self-reports correlate, estimates of
campaign effects will be biased upward, driving results to be at least partly spurious (Vavreck
2005).
While fully correcting these problems with observational cross-sectional data is not
possible we can introduce some additional steps to our analysis that allow us to diagnose the
extent to which they affect our analysis and also to ameliorate some of their effects. In
addition it is worthwhile to note that survey do possess some strengths as well as weaknesses
for investigating questions of voter mobilization.14 One obvious means of reducing the
problem of over-reporting introduced by survey data is to rely on validated turnout data. We
have these data for the UK sample and replications of our models using validated vote do not
show any significant changes to our results. However, as Vavreck (2005) has shown, biases
in estimation are typically driven by errors in self-reports of campaign contact, not errors in
self-reports of turn-out. Furthermore work by Berent, Krosnick and Lupia (2011) has found 11 A survey is, in effect, an all-at-once self-report of what is happening inside respondents’ heads at the single time point of the interview and thus do not provide an ideal basis for discriminating competing claims of causality. Experiments, in this view, are close to the “gold standard” for assessing causality 12 Source: The Electoral Commission: http://www.electoralcommission.org.uk/13 Source: United States Election Project: http://elections.gmu.edu/Turnout_2012G.html14 While experiments may constitute the ‘gold standard’ for addressing questions of causality, randomized surveys are the optimal method for assessing distributions of opinions and behaviors in populations. As such, survey-embedded experiment may be the ideal combination for the type of analyses we undertake here. In the absence of such data, however, and given our main interest in this inferences to the population we opt for the survey approach while maintaining caution on any claims of causality.
10
that over reporting is much less frequent than assumed and that over self-reports of turnout
may be more accurate than vote validation. Validated turnout data can introduce new sources
of error resulting from erroneous government-records that in some cases might be even more
severe than errors associated with self-reported behaviour.To the extent that we can address
the problems in likely over-reporting of campaign contact we apply two main measures. First
we introduce a control for whether the voter resides in a battleground state in the US or a
marginal constituency in the UK on the basis that those in close fought campaigns are more
likely to over report campaign exposure than those in non-battleground states. Second, we
add a measure of civic duty which as Vavreck (2005) has shown in a large field-experiment,
is the variable that is most potent in purging correlations between errors in self-reported
political activities. All our models include this predictor in order to keep correlations of the
errors at a minimum.
Having implemented these corrective steps we proceeded to examine our first two
hypotheses dealing with the effect of contact on turnout. Given our dependent variable is a
dichotomous measure of voting, binary logistic regression was used as our estimation
method. Our main independent variables are the four types of contact, direct online and
offline and indirect online and offline in the U.S. and the three available to us in the UK
BMRB data. Each of these is dichotomous, coded 1 if the respondent had been contacted in
that fashion. Given that the UK model lacked a measure of offline indirect contact we
included an indicator of political discussion as a proxy to capture and control for some of its
effects. A standard set of demographic and attitudinal controls were included in all models:
gender, age, education, socioeconomic status (income in the US, social class in the UK),
interest in politics and strength of party identification. For all models age was measured in
categories (18-34; 35-54 and 55+). This was done to ensure comparability across the models
since age was not available as a continuous variable in the ANES due to privacy restrictions.
The reference category in all models is the ‘middle’ age group (35-54). The U.S model also
included controls for race (Hispanic and black). Finally given the interesting differences we
observed in the age profile of those receiving online contact across the two countries we
added interaction terms between contact type and age. Essentially this variable was designed
to explore whether the effects of different types of contact were more effective among older
or younger people.
To control for campaign intensity and also the likely over-reporting of contact as
noted above, dummy variables were added to indicate a marginal constituency (UK) or
battleground state (US). Finally we included a measure of whether the respondent had signed
11
up to receive online information from the campaign. Crucially this variable allowed us to
control for the likely the self-selection effect associated with direct online contact and thus
more accurately assess its mobilizing effects. Full details of the wording and coding of all the
variables can be found in the appendix.
The results of the turnout models are reported in Tables 4 and 5. Both tables report
two models, the first being the basic model and the second with the interactions added. A
general point to note is that in both countries our control variables are largely statistically
significant, substantively strong, and appropriately signed.
Tables 4 and 5 about here
The results of the basic model in the UK (Table 4) show that as expected offline direct
contacting has the strongest effect on turnout with no other mode of contact proving to be
significant. Our proxy for offline indirect contact, discussion is also positive and significant
although as noted this refers to a much broader type of political ‘talk’ than our concept of
indirect contact specifies. The effect of online direct contact, while not significant, is
surprisingly large in comparison to the other modes including offline direct. While this might
suggest rejection of H2 the estimate is seen as unreliable due to the very small N associated
with this variable, something which is supported by its large standard error in both models.
When we add the interactions with age in model 2 the impact of offline direct contact remains
positive for all age groups although none are now significant, a change that is most likely due
to the reduced N in each category and loss of statistical power. More interesting changes are
observed in the impact of indirect online contact by age. Here we find that younger people
who received digital messages from friends and family were significantly more likely to vote
than those aged 35-54. This finding holds even controlling for prior sign-up. In a further twist
the effect of offline indirect contact for the middle age group which as the reference category
is now the ‘main’ effect becomes negative and significant indicating that this age group are
actually less likely to turnout to vote after receiving this type of informal online contact. This
result is somewhat surprising and cannot be fully explained through these data. One
explanation might be that this age group are the ‘digital immigrants’ who do not experience
the internet and social media as a natural extension of their daily life (as do younger digital
natives) and who also rely most heavily on it in their professional lives. Thus they may be
inclined to regard political messages received through their social network or email as
inappropriate and/or intrusive on their time and to react negatively.
12
Turning to our turnout model for the U.S. (Table 5) we find that as expected the ‘gold
standard’ of direct offline contact is significant and has the strongest effect on turnout.
Indirect offline contact is also positive and statistically significant. When we add our age
interactions the main effects of offline direct and indirect contact remain positive and
significant indicating that it is among the middle age group where these effects are most
strongly observed. Interestingly the effect of offline direct contact for the oldest voters
becomes negative indicating that its impact for this group is significantly lower than for the
middle age group. As in the UK no online methods are significant in our initial model,
however, when the interaction terms are added we again do see differences by age, with
online direct contact being significant for older voters after controlling for prior sign-up. This
finding is interesting and may be explained by the fact that older voters would be more used
to receiving offline contact from parties than the other age groups and so would be more
likely to experience the online version as a new phenomenon and respond to it.
In terms of our first two hypotheses, therefore, both cases appear to support H1 with
the U.S. providing the strongest and most consistent support for the importance of traditional
modes of contact on voter mobilization. The results for H2 are largely inconclusive in the
UK, while in the U.S. is it more clearly rejected in that while on first glance direct online
contact appears to have the weakest impact on voters overall, when we look across age
groups it appears to have a particularly strong effect among older voters.
Moving on to the campaign participation models we followed a similar modelling
strategy whereby we ran basic models and then more complex versions with age interactions.
For the UK we switched to use the BES dataset since BMRB lacked a measure of campaign
participation. This introduced certain constraints to the model which reduced its accuracy and
robustness. Firstly, while we retained specific measures of online and offline direct contact
we could not distinguish indirect contact by mode since the BES question did not specify
how friends and family had contacted the respondent. In addition we lacked the ‘sign-up’
variable which controlled for selection effects in receiving online direct contact. Finally the
dependent variable was measured through expectation of future involvement on a scale of
zero to 10 rather than actual behaviour. Diagnostics revealed this variable was highly
positively skewed (61% of the sample reported the lowest likelihood of engagement) which
meant negative binomial regression was substituted for OLS. In the U.S. analysis we used a
dichotomous variable measuring whether the respondent had worn a campaign button or
bumper sticker, attended a rally, given money to either party or candidate, or done other work
13
for candidates. Similar to other recent U.S. campaigns, 22% of the sample reported having
done at least one of these campaign activities.
The results for the UK are reported in Table 6. In general we find fewer controls are
significant than in the turnout model although political interest and strength of party
identification remain strong and significant (this is true also for the U.S.). More importantly,
however, the results show that in contrast with the turnout model, the importance of offline
direct contact disappears and indirect contact comes to the fore, as does direct online contact.
Once the interactions are added indirect contact is found to be particularly influential for the
middle age group while for younger people the sign is negative and significant indicating that
young people are substantially less likely to sign up to help a campaign based on this type of
contact than older voters. The effect of online direct contact disappears entirely. While this is
likely due to the N becoming too small across age groups to detect effects, a major caveat is
attached to concluding any mobilizing effect for direct online contact in this model to begin
with given the lack of the prior sign-up variable. While this variable was not significant when
included in the BMRB turnout model (Table 4) one can argue that it is likely to be a
particularly common action among those who would help a campaign and so is more likely to
be significant here. Overall then the findings provide qualified support for H3 and H4 in the
UK. Evidence exists to support an effect for online direct mobilization but there is no
evidence to suggest that offline direct contact mobilizes campaign activity. Also it appears
that online direct contact is more relevant to campaign participation than turnout. The main
finding from the model that was not predicted by our hypotheses, however, is that political
messages mediated through conversations and interactions with friends and family are most
likely to stimulate involvement in the campaign than those coming from parties themselves.
Unfortunately we cannot determine whether it is online or offline interactions are provide the
strongest stimulus since the BES did not differentiate this type of contact by mode.
The results for campaign activity in the U.S. are presented in Table 7. The first model
shows that offline direct contact remains the strongest and indeed only significant predictor
of whether someone volunteers to help a candidate or party. When we then parse the effects
by age we see that the mobilizing effects of offline direct contact are concentrated in the over
55’s. Even more interestingly, however, is the fact that the effects of both direct and indirect
online contact now become evident. Online direct contact emerges as significant in
mobilizing campaign participation, particularly among people aged 35 to 54. Interestingly its
effects are significantly lower for those over 55, which runs somewhat counter to the
previous findings of stronger effects for online contact on turnout among older voters. Thus,

it seems that while older voters will respond to online messages as an encouragement to vote
they clearly need a push through more conventional face to face methods to get them active
in the campaign.
Online indirect contact also appears to vary in importance for age groups but appears
to be particularly influential among young people (18-34). While this would seem to run
counter to the UK findings that indirect contact was significantly less important for younger
voters than those who are mid-aged, it is not possible to directly compare with the UK here
since the indirect contact variable mixed both online and offline forms and it may have been
if they were separated that similar findings emerged. Overall the results from the U.S. on
campaign participation provide partial support for H3 in that in a ‘straight fight’ offline
contact beats online contact in absolute mobilizing power, however when we break down
their effects by age group it seems that while offline direct contact matters most for older
respondents, online direct is actually more important (based on the size of the coefficients)
for the mid-aged group. Furthermore and in an unanticipated finding, online indirect is
actually most influential for the youngest voters. Finally, in regard to H4 the story is also not
clear cut in that the findings from the basic models show that online direct contact is not
influential in mobilizing either turnout or campaign participation. However, again age
moderates this conclusion in that the effect of online direct contact by parties among voters in
the mid 30s to mid 50s appears to actually be much more influential in mobilizing campaign
participation than turnout.
Discussion and Conclusions
This analysis has sought to understand how widespread and effective online methods of voter
contact are in comparison to offline methods and across different national contexts. Our
findings have shown that although direct or official online contact from parties and
candidates typically reach a smaller audience than offline methods, the gap is much smaller
in the U.S. than in the UK, indicating that American campaigns retain their vanguard status in
the adoption of new electioneering technologies. We have also found that U.S. campaigners
are reaching a more diverse audience with their online messages that is quite similar to those
receiving more traditional forms of contact. This convergence suggests online voter
communication is becoming more mainstream, at least in U.S. national elections. One caveat
to the country divide that emerged is in rates of informal online political contacting which is
much higher in the UK than that from parties and comparable to U.S. levels. Thus it seems
15
that while UK parties have not yet ‘bought’ into digital communication with voters, the
voters themselves are quite comfortable in sharing election related information online.
In terms of impact our expectations are largely confirmed in both countries with
offline contact from parties emerging as most influential in mobilizing turnout among the
electorate as a whole. It is not possible, however, to entirely dismiss an effect for online
contact which does appear to be able mobilize certain segments of the electorate, particularly
older voters in the U.S. Our expectations for campaign participation are also broadly
supported in that the effects of online direct contact appear to be stronger than for turnout,
again particularly for voters in the U.S.
In the course of the research some unexpected but highly interesting findings emerged
about the effects of indirect contact. This mediated messaging was important in mobilizing
both turnout and campaign participation. Most notably the online version was particularly
important in mobilizing younger voters to get involved in the campaign. These findings are
exciting in that they signal that the internet may be reviving the ‘two-step’ flow model of
voter communication and presenting new opportunities to reach an important demographic
group that are typically seen as more disengaged. As well as expanding the comparative
focus of this analysis and examining the impact of online and offline forms of contact outside
of the UK and U.S., future research should also look more closely at disaggregating the
mobilizing effect of different modes and sources of contact to see if this more nuanced
pattern holds elsewhere.
