Good for them! This story is from Politico:
Stephen Colbert’s satirical run for the presidency has run into its first roadblock — his bid to be on the ballot in the South Carolina Democratic presidential primary was rejected on Thursday.
The party’s executive council voted 13-3 to refuse Colbert’s application for a spot on the ballot.
“The general sense of the council was that he wasn’t a serious candidate and that was why he wasn’t selected to be on the ballot,” said Joe Werner, the party’s director. “There was discussion — I wouldn’t call it a heated debate — but there was discussion about it.”
If Colbert wants to run a pretend campaign on his show, that's his business. But lets leave these serious issues to the serious candidates.
