Redistricting in South Carolina

Here’s how new congressional maps shift voting power in every state

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.

How the new map shifts voting power by demographic

The Palmetto State will continue to hold seven seats in the House. Under its new map, South Carolina’s 6th District, between Charleston and Columbia, has been redrawn and is no longer a Black-majority seat.
