Mark Sanford of Appalachian Trail fame is running to retake his old seat (SC 1), as Nancy Mace is stepping down to run for governor. He has entered a crowded Republican primary. This market will resolve YES if Mark Sanford is elected to the House on November 3, and NO otherwise. (In theory this is district-agnostic -- if he pivots and runs in Georgia or something and wins, this will still resolve YES, because that would be funny). Initializing at 25% for reasons I feel to be self-evident.
