South Carolina's 6th congressional district remains a solidly Democratic seat, reflected in trader consensus around a 95% probability for the Democratic nominee. Incumbent Jim Clyburn advanced easily through the June 2026 Democratic primary with over 90% of the vote and faces Republican nominee John Peterson in the November general election. The district's D+13 partisan voter index, demographic composition, and consistent performance in recent cycles underpin the wide gap. Forecasters across outlets rate the race as safe or solid Democratic, with no successful redistricting changes altering boundaries before primaries. Clyburn's decades of incumbency and established voter base in the Columbia and North Charleston areas further anchor expectations. A narrow path for Republicans would require an unprecedented swing in turnout or late-cycle events capable of overcoming the structural lean.
