South Carolina's District 1 Congressional race is down to two candidates.
Former South Carolina Gov. Mark Sanford and Curtis Bostic are vying for the Republican nomination. Last Tuesday, they were the top voter-getters. They'll debate Thursday at Porter Gaud High School in Charleston.
The runoff is April 2. The winner will take on Democrat Elizabeth Colbert- Bush in the election in May.
