PartyPolarization

ThereisclearevidenceofpartypolarizationattheelitelevelofAmericanpolitics.Polarizationistypicallydefinedintermsofagrowingideologicalgapbetweenthetwomajorpoliticalpartiesandincreasedideologicalhomogeneitywithinparties.Forexample,studiesofCongressfindthatthecenteroftheDemocraticPartyhasmovedtotheleftwhileRepublicanlegislatorshavemovedmoresharplytotheright,particularlyduringthepasttwodecades(Bonicaetal.2013;Theriault2013).Inaddition,studiesofpartyactivistsfindgrowingdifferencesbetweenDemocratsandRepublicansoneconomic,racialandculturalissues(Laymanetal.2010).Finally,recentexaminationfindsaconsiderabledegreeofpartypolarizationinAmericanstatelegislatures(ShorandMcCarty2011).

Thereissomedebateabouttheextentofideologicalpolarizationamongthemasspublic.Some,suchasFiorinaandcolleagues(2011)arguethatmostvotershavecentristpolicypreferencesthathavenotchangedmuchintheaggregateinresponsetoelitepolarization.However,severalotherstudiesobservegrowingdifferencesbetweenRepublicansandDemocratsonarangeofissues(e.g.,Abramowitz2010;Laymanetal.2010).Increasedelitepolarizationmeansthatelectedofficialsmorefrequentlydividealongpartylinesonimportantissuesoftheday.Theincreasingfrequencyandintensityofthesepolicydisagreementsmakethepublicmoreawareofpolicydifferencesbetweenthemajorpoliticalparties(Hetherington2011).Beingawareofthemajorpolicydifferencesbetweenthepartiesmakesiteasierforcitizenstochoosesidesinthepartisanpoliticalwars.

Socialidentitytheoryarguesthatpeoplederivetheirownsenseofselffromtheirmembershipingroups.Themotivationtoidentifywithanin‐group(towhichthepersonbelongs)thatisdistinctfromaperceivedout‐groupispowerful(Tajfel1978,1982).Asaresult,peoplenaturallytendtoseetheworldintermsofin‐groupsandout‐groups.Moreimportantly,thetheorypredictsbiasedperceptionsthatexaggerateinter‐groupdifferencesandgeneratepositivefeelingstowardone’sowngroupandnegativefeelingsaboutopposinggroups.PartyidentificationisacentralconceptinthestudyofAmericanvotingbehavior,andwasoriginallyconceivedtoresembleothersocialgroupidentities,likereligion(Campbelletal.1960).Thus,socialidentitytheorymayhelpusunderstandpartisanshipandpartypolarization.

Severalstudiesexaminepartisanshipfromtheperspectiveofsocialidentitytheory.Mostimportantly,aselitepartypolarizationisconveyedtothepublic,citizensbecomemorecertainabouttheirownpartyidentity(Lavine,Johnston,andSteenbergen2012;Druckman,Peterson,andSlothuus2013).Similarly,Greene(1999)findsthatstrongpartisansstandoutfromotherpartisansintermsoftheirrobustsocialidentitywithapoliticalparty.Furthermore,socialidentitypredictsvoterloyalty,activism,andideologicalextremismevenwhencontrollingforstrengthofpartisanship(Greene2004).Morerecently,Iyengar,Sood,andLelkes(2012)applysocialidentitytheorytodocumentincreasingaffectivepolarizationinthemasspublicintheUnitedStatesandBritain.Forinstance,theyobserverisinglevelsofoppositiontointer‐partymarriageandincreasedpartypolarizationintraitratingsofpartysupporters.

CoreValues

Toappealtoasmanyvotersaspossible,politicalcampaignsfrequentlyframepolicydisputesintermsofcorevaluesorprinciplesthatcanbeappliedtoissuesinaparticularpolicydomain.Corevaluesaregeneralbeliefsabouthowtheworldshouldwork,andvaluesguideaperson’sunderstandingofrightandwrong.Totheextentthatpartisanpoliticaldebatesareframedintermsofclashingvalues,thenpartisansareencouragedtoviewthoseconflictsintermsofrightversuswrongandgoodversusevil.Ifdifferentpartiesrepresentcompetingvalues,ordifferentpolesonthesamevaluedimension,thencorevaluesmaystructureaffectivepolarizationintheUnitedStates.

Corevaluesarewidelyheldandusedbyvoters.Virtuallyallcitizens,regardlessoftheirlevelofeducationorinvolvementinpolitics,adheretoalimitednumberofcorevaluesandareabletobasetheirownvotingdecisionsandpolicypreferencesonthosevalues(Feldman1988;Goren2013).Sincefirmlyheldvaluesmayconflictwithoneanotheronsignificantpublicpolicydebates,valuesarelikelytostructurepartisanconflict.Asaresult,valueconflictmaybeanimportantsourceofattitudepolarizationinAmericanpolitics.WeexaminethreecorevaluesthathavebecomecommonsourcesofpartisanconflictinAmericanpolitics:egalitarianism,limitedgovernment,andmoraltraditionalism.4

Corevaluesaredistinctfromleft‐rightideologyassourcesofpartisanconflict.Whileeachofthevaluesdescribedabovecanbemappedontotheliberal‐conservativespectrum,noneofthemareperfectlycorrelatedwithideology.Moreimportantly,peoplewhomaynotcomprehendtheliberal‐conservativeframeworkofideologicalconflictcanapplycorevaluestovotingandpolicydecisions.Andsincecorevaluesformthebasisforbeliefsaboutrightandwrong,valuesarecrucialfornurturingnegativeviewsofthepoliticalopposition.Itisnosurprisethatpartisanrhetoricfrequentlytapsintocorevalues.ThequotationsfromPresidentObamaandGovernorRomneyatthebeginningofthispaperoffertwoexamplesofvaluereferencesduringthe2012presidentialcampaign.Obama’sstatement,madeinconnectionwithhisannouncedsupportforlegalizinggaymarriage,containsegalitarianthemes.Romney’sstatement,madeattheannualconventionfortheNationalRifleAssociation,emphasizeslimitedgovernment.Insum,valueconflictshouldhelpexplainpolarizedratingsofthetwoparties.Thosewithmoreextremebeliefsoneachvaluedimensionshouldproducemorepolarizedratingsofthetwomajorparties.

Wealsobelievethatattitudestowardsocialgroupscontributetopolarizedratingsofthetwopoliticalparties.AttitudestowardgroupsareanimportantsourceofpolicypreferencesintheUnitedStates.Partisanrhetoricisfrequentlyframedintermsdesignedtoappealtopublicstereotypesofprominentgroupsinsociety.Inaddition,sometheoriesofpartisanshiparerootedinpublicperceptionsofsocialgroupscommonlyassociatedwitheachpoliticalparty(Jacoby1988;Green,Palmquist,andSchickler2002).Asisthecasewithcorevalues,peoplewhodonotfollowpoliticsverycloselycanstillformbeliefsaboutgroupsinsocietyandrelyonthosebeliefstoevaluatethepoliticalparties.Wefocusonattitudestowardtwogroupsthatreflectimportantpartisandifferencesinmodernpolitics:AfricanAmericansandwomen.

WealsoexamineattitudesinvolvingthestatusofwomeninAmericansociety.Modernsexismrevolvesaroundreactionstochanginggenderrolesandbeliefsaboutthedegreethatdiscriminationagainstwomenstillpersists(GlickandFiske2011).Thereisaconsistentgendergapinvotingandpartyidentification,withwomenmoresupportiveoftheDemocraticPartyandmenfavoringtheRepublicanParty(ClawsonandOxley2013).Furthermore,thereispersistentpartisanconflictoverissuesspecifictowomen,suchasabortion,contraception,equalpay,andworkplacerights.Forexample,theDemocraticPartyrecentlycampaignedonanallegedGOP“waronwomen,”highlightingsomeoftheseissues.The“waronwomen”rhetoriclikelystirsbeliefsaboutmodernsexismwhenvotersevaluatethetwoparties.Thus,attitudesabouttheroleofwomenarelikelytobeasourceofpolarizedratingsofthetwomajorparties.
