Stephen Colbert on Rick Santorum's Iowa Caucus Surge

I almost feel sorry for Colbert — there are just too many ways to mock Rick Santorum. His name is gross. He wears a goofy sweater vest. He refers to that sweater vest by saying stuff like "fear the vest." He's got a weird nasally voice that makes you wonder whether his whole "family values" persona isn't just an elaborate way to retroactively justify his never getting laid in high school. He's not going to win the presidency. Yep, I almost feel sorry for Rick Santorum.

Coverage continues after the jump as Stephen talks with an undecided Iowa Republican.

The Colbert Report airs Monday through Thursday at 11:30/10:30c.
