Politics and pop culture

Comedy Central host Stephen Colbert already started his own Super PAC, run ads in South Carolina and now with today's "The Rock Me Like a Herman Cain: South Cain-olina Primary Rally," he claims to be testing the waters for a presidential bid.

According to one poll -- and it appears to be the only poll that looked into the matter -- Colbert would garner 5% of the GOP vote in South Carolina's Saturday primary if he appeared on the ballot. So today we'll talk about jokes, politics, entertainment, news and no doubt Pat Paulsen.

Marianne's guest are Danna Young, Assistant Professor of Communications at The University of Delaware, Jay Rath, a founding staff writer for The Onion, and Geoffrey Baym, a professor of media studies at the University of North Carolina-Greensboro.
