Politics can make you think, act, scream or wince.

But comedian Stephen Colbert's politics can make you laugh, and apparently a lot of people are in need of a good chuckle.

Colbert and former GOP presidential candidate Herman Cain are holding the "Rock Me Like a Herman Cain South Cain-olina Primary Rally" at 1 p.m. today at the College of Charleston.

Calls from students and community members started pouring into the college Thursday as word spread that Colbert would hold a rally in the Cistern Yard, said college spokesman Mike Robertson. "Students are a little over-excited about it. We anticipate a big crowd."

Robertson said the Cistern Yard will be closed this morning so people who want to attend the free event can line up on the sidewalk. Gates open at noon.

There won't be any chairs at the event, which means more people can be squeezed into the Cistern Yard, he said. People will be admitted on a first-come, first-served basis.

Colbert said he has a lot in common with Cain.

Cain never ran a negative campaign ad, Colbert said on his TV show The Colbert Report. "He shares my values."

Colbert, who said he's considering entering the race, isn't on the South Carolina ballot. He did not file by the Nov. 1 deadline. Cain, who dropped out in December, remains on the ballot but isn't seeking the GOP nomination.

Still, Colbert is encouraging people to vote for Cain. "A vote for Herman Cain in Saturday's primary would be a strong message to me that voters want me to run," Colbert said on his show Wednesday.

Voters who want to deliver that message to him themselves should attend the rally, he said.

"This is real. It's happening Friday at 1 p.m.," he said.
