South Carolina’s seven U.S. House districts feature one safe Democratic seat held by Jim Clyburn and six Republican-held seats, with two open due to retirements. The open SC-1 race stands out as the sole plausible flip opportunity after Nancy Mace’s departure, drawing a Democratic challenger in a district rated R+6. Recent forecasts show the Republican nominee leading by roughly seven points in a national environment that has narrowed GOP margins elsewhere, though the seat remains lean Republican. Failed mid-decade redistricting efforts preserved existing lines, leaving no additional competitive districts. Trader pricing therefore centers on Democrats retaining their single seat while assigning meaningful but secondary probability to a SC-1 gain.
