South Carolina's entrenched Republican advantage in federal elections, reinforced by Donald Trump's 17.9-point margin in the 2024 presidential vote, underpins the strong trader consensus favoring the GOP nominee. Darline Graham secured the Republican nomination in the August 25 special primary runoff after her late brother Lindsey Graham's death prompted a new candidate process; her victory, aided by presidential endorsement and super PAC support, consolidated the party's base ahead of the November general election. Democrat Annie Andrews, a pediatrician who won her party's primary, confronts longstanding structural barriers, including the absence of a Democratic Senate win in the state since 1998. Recent polling averages reflect a Republican edge of roughly seven to nine points, consistent with the state's partisan fundamentals and limited crossover appeal for the challenger.
