Colbert wants supporters to vote for Herman Cain

Comedian Stephen Colbert announced last week he would be forming an exploratory committee to run for the "President of the United States of South Carolina." Unfortunately for him, he isn't on the ballot and South Carolina voting laws prohibit write-ins. But Colbert's Super PAC released an ad Monday which says "there is still a name on the ballot that stands for true Americanimity."

That name is Herman Cain, says the ad, while showing Colbert. Cain never actually shows up in the ad, in fact, but his name will still show up on South Carolina's Republican primary ballot.

Watch and laugh:
