Cheating Ex Gov To Battle Stephen Colbert's Sister For Congress

  • 04.02.13 08:53 PM EDT

A political newbie with a very famous surname, Elizabeth Colbert Busch, sister of the comedian Stephen Colbert, is the Democratic candidate for Congress in South Carolina. And now, it turns out she's running against another (in)famous candidate -- Mark Sanford, the former Republican governor who left office in disgrace after an extra-marital affair. The high-profile candidates make for an unusually popular race for an off-season Congressional election. 

The seat was vacated by Rep. Tim Scott, who was appointed to fill the seat of Sen. Jim DeMint, who stepped down to run the Heritage Foundation.

Sanford earned more than 35% of the vote in the March 19 Republican primaries, and then defeated his remaining opponent in a run-off on Tuesday April 2.

The seat is usually considered a Republican safe-seat -- but its fate isn't guaranteed, not just becuase of the Democrat's high-profile brother. Mark Sanford was drubbed out of office in 2009 after it was revealed that he was having an affair with an Argentinian woman, to whom he's now engaged. Sanford claimed that he was "hiking the Appalachian Trail" -- which, if nothing else, is a gift to the national discourse -- the phrase has since become synonmous with having an affair.
