Every 10 years, states redraw the boundaries of their congressional districts to reflect new population counts from the census. South Carolina’s Republican-controlled legislature drew a map that likely maintains the party’s 6-to-1 advantage in its US House delegation. The new map makes the coastal 1st Congressional District — the only one in the state that has been competitive in recent years — safer for Republicans by bringing more rural areas into the district. Rep. James Clyburn will likely still be the only Democratic representative from the Palmetto State.
