Incumbent Sheri Biggs holds a commanding position in South Carolina's 3rd congressional district due to the seat's strong Republican partisan lean, her unopposed primary advancement, and consistent "Solid Republican" or "Safe Republican" ratings from forecasters including the Cook Political Report, Inside Elections, and Sabato's Crystal Ball. The district's voting patterns and limited Democratic resources, reflected in Eunice Lehmacher's modest primary fundraising after her narrow June 2026 win, reinforce trader consensus on the outcome. The November 3 general election features a Libertarian candidate as well, but structural barriers such as the district's electoral history make an upset unlikely absent major developments like a late scandal, health event affecting the incumbent, or unprecedented national political shift.
