After yesterday's press conference, we all now know South Carolina Governor Mark Sanford a lot better. I feel like I know him better than I know my own wife. I certainly don't know how many Argentine women she's slept with. Of course, Stephen Colbert was way ahead of the curve. As you'll see in this clip, he was better-knowing Mark Sanford long before it was hip. And after the jump, you can see the full 2008 interview.

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