Always seeking to enhance their journalistic credentials, Fox News has recruited a new contributor that will bring a unique insight to their political analysis.

Mark Sanford, the former Republican governor of South Carolina, has been added to the Fox News team. Sanford, you may recall, was the wayward governor who went missing and, after initial reports from his staff that he had taken a hike on the Appalachian Trail, it was eventually learned that he had slithered down to Argentina for a rendezvous with his mistress.

This hire may surprise some observers who recall Fox criticizing CNN for hiring former New York governor Eliot Spitzer. But there are notable differences between the two fallen pols. Sanford disappeared without informing anyone of his whereabouts, and his unfaithfulness resulted in divorce and a broken home. Spitzer, on the other hand, never abandoned his duties as governor, and he managed to preserve his marriage after it was revealed that he had patronized a Washington call girl.

Kudos to Fox News for snagging a forthright voice for infidelity that is too rarely represented in the media. He will join a fraternity of Fox fellows who have fractured marriage vows including Karl Rove, Newt Gingrich, Dick Morris, Roger Ailes, and the original sinner, Rupert Murdoch, who is on his third wife.

No wonder Fox is regarded as the network of family values. They apparently believe people should have as many families as possible. That may prove to be an advantage for Mitt Romney, the Mormon in the GOP presidential primary.
