Incumbent Rep. Nancy Mace's departure for the 2026 South Carolina gubernatorial race has left SC-01—an open, Solid Republican district per Cook Political Report ratings—as a prime test of GOP strength ahead of the June 9 primaries. Trader consensus at 75% for the Republican nominee reflects the district's strong partisan lean (Trump +13 in 2024), historical incumbency advantages, and a crowded primary field featuring former Gov. Mark Sanford's late March filing alongside well-funded challengers like Sam McCown. Democrats, led by Mac Deford, have recruited a full slate but face uphill battleground dynamics and weaker fundraising; upcoming primaries could consolidate GOP support, with any nominee favored barring national midterm shifts.
