Incumbent Republican Senator Lindsey Graham's recent filing for re-election on March 16, backed by President Trump's endorsement and a massive $13 million war chest, solidifies trader consensus pricing Republicans at 80.5% to retain South Carolina's Senate seat in the deep-red state. Early general election polls, including a February 25–March 1 Impact Research survey showing Graham leading Democratic pediatrician Annie Andrews 47%-42%, reflect his incumbency edge despite some GOP base dissatisfaction. Fragmented Democratic primary fields and Republican challengers like Paul Dans and well-funded Mark Lynch face long odds in the June 9 primaries, per ratings from Cook Political Report (Solid R) and Sabato's Crystal Ball (Safe R). With filing deadline tomorrow, no seismic shifts have emerged to challenge the historical Republican stronghold since Democrats' last win in 1998.
