Incumbent Republican Sheri Biggs's bid for re-election in the solidly Republican South Carolina 3rd Congressional District (Cook PVI R+21) drives trader consensus to 92.5% odds favoring the GOP, reflecting her 2024 general election landslide (72%) and Trump’s 71% district margin that year. With no declared primary challengers as of late March filing deadline, Biggs holds a fundraising edge ($211,000 cash on hand), while Democrats Eunice Lehmacher and Ernest Mackins face a low-resource primary on June 9. Forecasters rate the seat Safe Republican, underscoring weak Democratic path absent a GOP scandal, health issue, or extraordinary national midterm wave shifting turnout in this non-battleground. Libertarian Brian Corriea qualified April 11 but poses minimal threat. General election: November 3.
