South Carolina's 3rd congressional district remains a structurally Republican stronghold, which aligns with the current trader consensus favoring the Republican nominee at 90.5 percent. Incumbent Representative Sheri Biggs secured the seat in 2024 with a substantial margin and enters the June 9, 2026, Republican primary without notable opposition, while Democratic contenders such as Eunice Lehmacher compete in a low-visibility primary for a district rated safe Republican by multiple analysts. This positioning reflects the area's consistent partisan lean exceeding 20 points in recent cycles and the limited resources available to Democratic challengers. Scenarios that could realistically shift probabilities include a successful congressional redistricting effort altering district lines, a significant scandal or health event involving the incumbent, or a broader national political shift before the November 3 general election.
