(CNN) - Following his big rally endorsing Herman Cain for president in South Carolina last week, comedian Stephen Colbert announced Monday he was calling it quits.
"My fellow Americans of South Carolina: While your turnout on Saturday was historic, unfortunately–and no one could have predicted this–Herman Cain did not win the South Carolina primary," Colbert said on his Comedy Central show.

He added: "So it is with a heavy heart and a spastic colon, that I am re-suspending Herman Cain's suspended campaign."
Colbert had tried to get his name on the Palmetto State ballot, but since he missed the November filing deadline and because the state doesn't allow write-in votes, Colbert urged supporters to vote for the former Godfather's Pizza executive in his stead.
Cain suspended his campaign last month but his name remained on the ballot.
The faux TV news host also announced plans to end his own short-lived White House bid, saying he was shutting down the presidential exploratory committee he started nearly two weeks ago - members of which, he joked, included Henry Kissinger, a "super intelligent" ferret, the iPhone software Siri, and a roll of quarters.
"So now that my exploration has come to an end, who knows what I'm going to do. Maybe I'll be like Herman Cain and hit the road in a bus with my face on it," Colbert said. "Maybe I'll hit the road in a bunch of tiny cars, each with a different part of my face on it."
