He's Back: Mark Sanford to Run for Congress Could end up running against ex-wife By Matt Cantor, Newser User Posted Dec 21, 2012 1:32 AM CST 19 comments Comments In this Jan. 19, 2012, file photo, former South Carolina Gov.

Tim Scott grabbing Jim DeMint's old Senate seat, there's a vacancy in South Carolina's congressional delegation—and a former governor wants in, CNN reports. Republican Mark Sanford, who was considered a presidential contender before his extramarital affair became national news, is "all but certain" to seek the seat he held in the 1990s, a former aide says. Sanford's history of serving the state could help him in the likely March primary, and he still has $124,000 in his campaign coffers. But a majority of the state has an unfavorable opinion of him, according to polls. Things could get interesting, notes the Washington Post: It's possible Sanford's ex-wife, Jenny, could also be in the running.
