South Carolina

South Carolina Gov. Henry McMaster (R) took over the top job after Nikki Haley became the Trump administration's UN ambassador in 2017. Now he's up for his first full term against Democratic combat veteran and state Rep. James Smith. McMaster is the favorite to win re-election in this deep red state. The state's most competitive House race is expected to be in the 1st District, where Rep. Mark Sanford (R) lost his primary to state legislator Katie Arrington. Arrington is the favorite against Democratic attorney Joe Cunningham in the Charleston-based district, but a strong performance by Democrats could challenge that.
