CHARLESTON — Former Gov. Mark Sanford and former Charleston County Councilman Curtis Bostic are set to meet in a debate less than one week before the GOP runoff in the state’s 1st Congressional District.


The two are scheduled to meet Thursday night in Charleston.


Sanford was the top vote-getter in last week’s GOP primary. Bostic finished second in the 16-candidate Republican field.


The winner of Tuesday’s GOP runoff meets Democrat Elizabeth Colbert Busch in a special election in May.


The seat was left vacant when Rep. Tim Scott was appointed to the U.S. Senate seat once held by Jim DeMint, who resigned to head a conservative think tank.


Sanford is trying to make a political comeback after his public career was derailed four years ago after he admitted an affair.
