COLUMBIA, S.C. reports that 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 and said he will resign as head of the Republican Governors Association.

Gov. Mark Sanford with his family
“I’ve let down a lot of people, that’s the bottom line,” the 49-year-old governor said at a news conference where he choked up as he ruminated with remarkable frankness on God’s law, moral absolutes and following one’s heart. His family did not attend.
The woman, who lives in Argentina, has been a “dear, dear friend” for about eight years but, Sanford said, the relationship didn’t become romantic until a little over a year ago. He’s seen her three times since then, and his wife found out about it five months ago.
“What I did was wrong. Period,” he said.
According to Wikipedia Marshall Clement “Mark” Sanford, Jr. (born May 28, 1960) is is an American Republican politician who has been Governor of South Carolina since 2003.
In 1994, Sanford entered the Republican primary for the Charleston-based 1st Congressional District in the United States House of Representatives. The seat had come open after four-term incumbent Arthur Ravenel gave it up to make an unsuccessful run for governor. Despite having never run for office before, he finished second in a crowded primary behind Van Hipp, Jr, a former George H. W. Bush Administration official. Sanford defeated Hipp in the runoff, and breezed to victory in November. He was reelected twice, both times facing only minor-party opposition.
While in Congress, Sanford was a staunch conservative (he garnered a lifetime rating of 92 from the American Conservative Union), but displayed an occasional independent streak. He often would be one of two members of Congress, along with Ron Paul, voting against bills that otherwise got unanimous support.[citation needed] For example, he voted against a bill that preserved sites linked to the Underground Railroad.[4] He opposed pork barrel projects even when they benefited his own district; in 1997 he voted against a defense appropriations bill that included funds for Charleston’s harbor. Seeing himself as a “citizen-legislator,” he did not run for reelection in 2000, in keeping with a promise to serve only three terms in the House.
Sanford was listed in the House roll as “R-Charleston,” even though he lived on Sullivan’s Island.
As early as January 2008, there has been anticipation that Mark Sanford would run for President in 2012, and online support groups have sprung up on virtual social networks like Facebook in support of a Sanford ticket.
Further boosting Sanford’s profile in advance of a potential candidacy, which the governor has neither ruled out nor expressly hinted at,[50] he was elected as Chairman of the Republican Governors Association in November 2008[51] and was cited by Michael S. Steele, the Chairman of the Republican Party as one of four “rising stars” in the GOP (alongside Governors Bobby Jindal of Louisiana, Tim Pawlenty of Minnesota and Sarah Palin of Alaska) in February 2009.[52]
On February 22, 2009, Governor Sanford declined to rule out a possible presidential bid in 2012, though he professed to have no current plans to run for national office.
Some in the media believe that Sanford’s affair and subsequent brief disappearance may damage any possible presidential aspirations.
