Colbert, host of "The Colbert Report" and a native of Charleston, S.C., and Cain, the former Godfather's Pizza chief executive who dropped out of the race after allegations of sexual harassment and a 13-year affair, held the "Rock Me Like a Herman Cain: South Cain-olina Primary Rally" at the College of Charleston, The New York Daily News reported Friday.
The event featured appearances from both personalities as well as a gospel choir, cheerleaders and a marching band playing LMFAO's "Party Rock Anthem."
The event stemmed from Colbert's announcement this week that he is exploring a presidential run as part of his ongoing satire of the role super PACs have played in the current race.
The men told voters a vote for Cain, who did not drop out in time to get off the South Carolina ballot, would be a vote for Colbert.
"Mr. Colbert could not get on the ballot. I could not get off the ballot. That's how this came about," Cain said.
Colbert promised to keep the event positive and free from personal attacks.
"I won't be saying things like, 'The only difference between Mitt Romney and a statue is the statue never changes his position,'" Colbert joked.
"And I am not going to answer the 'gotcha' question, 'Are you interested in an open marriage?'" he said. "Though I am flattered Newt Gingrich asked me."
