Types of run-on sentences

FUSED

There is NO punctuation between the two independent clauses

COMMA SPLICESThere is a COMMA placed between the two

independent clauses

Obama held his acceptance speech at Grant Park in Chicago, there were thousands ofadmirers in attendance at the event.

Is this a run-on sentence? Obama used the Internet to reach out to

many people, consequently many people voted for him.

YES! The word consequently is a conjunctive

(connecting) adverb which cannot be used to connect two independent clauses.

Sometimes comma splices are created in this way.
