Could Mark Sanford re-enter politics?

Former South Carolina Gov. Mark Sanford, who resigned in 2011 after admitting to a partially tax-paid affair with an Argentine woman, indicated to the Associated Press that he would be interested in running for Congress again. Republican Rep. Tim Scott’s district is now open, after he was appointed to fill just-resigned Sen. Jim DeMint’s seat. Making things even more interesting, Sanford’s ex-wife and former campaign manager, Jenny Sanford, has also said she is considering a run for the seat.
