Trader consensus heavily favors the Republican Party at 92.5% implied probability for South Carolina's 3rd Congressional District House seat, reflecting the district's extreme conservative tilt with a Cook Partisan Voter Index of R+21—ranking 28th most Republican nationally—and incumbent Sheri Biggs's commanding 71.8% victory margin in 2024 amid 71% Trump support. Biggs faces no Republican primary challengers ahead of the June 9 contest, while Democrats Eunice Lehmacher and Ernest Mackins compete in a low-fundraising primary (Lehmacher raised $19,000 vs. Biggs's $400,000). Race ratings from Cook Political Report, Inside Elections, and Sabato's Crystal Ball uniformly deem it Solid or Safe Republican. Upsets remain possible via unforeseen scandals, health issues for Biggs, or a massive Democratic national wave, though structural barriers make these improbable before the November 3 general election.
