South Carolina's strongly Republican electorate, where Donald Trump carried the state by nearly 18 points in 2024 and no Democrat has won a U.S. Senate seat since 1998, underpins the heavy favorite status for the GOP nominee. Darline Graham, appointed to complete her late brother Lindsey Graham's term after his July 2026 death, secured the Republican nomination in an August 25 runoff against Rep. Ralph Norman with President Trump's endorsement and substantial outside support. Democrat Annie Andrews, a pediatrician, faces structural headwinds in a state that last elected a Democratic senator decades ago. The compressed special primary process following Lindsey Graham's passing consolidated Republican support behind the appointee well ahead of the November general election.
