Colbert tries to sever South Carolina ties after his sister loses House race

"I just feel so betrayed by South Carolina. Well, if they're going to turn their backs on my family I'm turning my back on them. From now on, and I never though I'd say this, I am from North Carolina. I have to, I have to. I'm a Tarheel now, whatever the f--- that means," Colbert said on his television show Wednesday night.

After choking down some "sauce-less, vinegar-based meat product that they call barbecue," however, Colbert relented.

He also joked about Sanford's campaign, wondering if she held "too few debates against a cardboard Nancy Pelosi."

"The voters of South Carolina have spoken. Mark Sanford beat my sister and I believe that means Mark Sanford is now my sister. And on behalf of my entire family I want to say I'm deeply sorry about him. Now we know how Kevin Manson must have felt," he said.
