The story on South Carolina governor Mark Sanford is now out:

After going AWOL for seven days, Gov. Mark Sanford admitted Wednesday that he'd secretly flown to Argentina to visit a woman with whom he'd been having an affair. He apologized to his wife and four sons.

Some in the media are urging that this is not really a story. It could have happened to anyone, which is true. And when it happens to most politicians it isn't much of a story in my opinion. On the other hand, it's not every politician who preaches sexual purity, "family values." The Republicans have been thumping their chests and claiming moral superiority and that's a valid reason for skewering cheating Republicans. Andrew Sullivan points out the hypocrisy:

The party that has gone on and on and on to prevent me getting married, and prevent my own marriage from being recognized by the federal government is the party of David Vitter, Mark Sanford, Rush Limbaugh and Larry Craig. It's like taking lessons on sexual maturity from the Vatican. And, yes, Sanford was a dedicated opponent of gay couples being allowed to marry.
