Columbia, SC (WLTX) - Former Governor Mark Sanford is planning a reentry into politics, according to a report from CNN.

CNN reported on its website Thursday night that the former two-term governor of the stateintends to seek the soon to be vacantFirst Congressional District seat. Reporter Peter Hamby sources an unidentified former top aide to Sanford as sayingthe ex-governoris "looking all but certain to do it."

Theposition opened up when Governor Nikki Haley appointed Rep. Tim Scott to replace Jim DeMint in the U.S. Senate.

Sanford represented the First District from 1995 to 2001. However, since then, the district's boundaries have changed. When Sanford held the seat, it stretched from Charleston to Myrtle Beach; now, the district is from Charleston to Hilton Head.

Sanford, though, has substantial political support from the Charleston area,where he lives, and would go in to any race as a heavy favorite.

The report says a formal announcement could come soon. It also says his former wife, Jenny Sanford, is not expected to seek the seat.

If true, this would be a politicalfull circle for the governor. Late in his second term as governor, Sanford was seen as a rising political star in the GOP, and there was speculation hewas going to runfor president in 2012. But a scandal over his affair with an Argentinean woman in 2009ended talk of a political ascension, and Sanford left office in 2011 relatively quietly.

Slowly, though, Sanford has begun making more public appearances, and took a job as a contributor with Fox News--things which fueled rumors that he was mulling a return to politics.
