Why Sanford vs. Colbert Busch Could Be Competitive

Former Gov. Mark Sanford won a runoff election this week, securing the Republican nomination for South Carolina’s First Congressional District. He will face the Democratic nominee, Elizabeth Colbert Busch, in a May 7 general election.

The First District, which runs from Hilton Head Island in the south to north of Charleston, is solidly Republican, and typically a Congressional race in the conservative Lowcountry would provide little suspense: Republicans have held the seat since 1981.

But this election is not typical. [cont.]
