"Former South Carolina Governor Mark Sanford is the guy who told his wife he was going for a hike and then went to Argentina to see his girlfriend.

"My sister lost. How could this happen? I was so sure Lulu had won because CNN called it for Sanford." –Stephen Colbert on his sister Elizabeth Colbert Busch's failed congressional bid
