Incumbent Republican Sheri Biggs, who won SC-03 with 72% in 2024, holds a commanding position in this R+21 district after filing for reelection unopposed in the June 9 Republican primary following the March 30 filing deadline. Trader consensus at 92.5% for the Republican Party reflects the weak Democratic primary field of underfunded challengers Eunice Lehmacher and Ernest Mackins, alongside consistent Safe Republican ratings from Cook Political Report, Inside Elections, and Sabato's Crystal Ball. Scenarios that could shift odds include a late Republican primary entrant fracturing the GOP vote, a Democratic nominee surging with national party support amid midterm turnout swings, or unforeseen scandals affecting Biggs before the November 3 general election.
