Incumbent Sheri Biggs holds a commanding position in the SC-03 general election due to the district's consistent Republican lean, reflected in recent presidential baselines exceeding R+27 and nonpartisan ratings classifying the seat as solid or safe Republican. Biggs advanced unopposed through the June 2026 Republican primary after winning the open seat in 2024, while Democratic nominee Eunice Lehmacher prevailed in a close primary but faces structural headwinds including limited fundraising and the district's voting history. The November 3 contest features a Libertarian candidate as well, yet trader consensus aligns with the district's partisan baseline and incumbency advantage. Shifts could occur from unexpected late developments such as major scandals or turnout surges, though none have emerged in recent weeks to alter the outlook.
