Gov. Mark Sanford was cheating on his wife

Gov. Mark Sanford of South Carolina, who's resistance to the use of Stimulus funds to help his high-unemployment state made headlines, had me thinking he was stupid, and had many thinking he would challenge President Obama in the 2012 presidential race, admitted to cheating on his wife today after he was spotted at Atlanta Hartsfield-Jackson International Airport coming from Buenos Aires.

What does this do to his political fortunes? Well, he's already resigned from the Republican Governor's Association today. I think he can kiss any future presidential ambitions goodbye for now.

More soon.
