While South Carolina's first congressional district leans Republican, Sanford's tenure as governor — marred by an incident where he disappeared for days, allegedly hiking the Appalachian Trail, only to be discovered conducting an affair with an Argentine woman — has given Democrats hope.

On Wednesday, Sanford noted his Democratic opponent had never before held elective office.

“Right now, the thing that people do know is that she’s Stephen Colbert’s sister ... at the end of the day, he’s not on the ticket," Sanford said.

He also dismissed internal polls, provided by Colbert Busch's campaign, that showed the Democrat with an early lead.

"We’re going to have a debate on ideas," Sanford said. "I think that’s going to substantially change the polls.”
