South Carolina’s solidly Republican electorate and long history of GOP dominance in Senate contests underpin the strong trader consensus favoring a Republican victory in the November general election. The death of incumbent Lindsey Graham in July triggered a compressed special primary process that concluded with his sister Darline Graham securing the nomination in an August 25 runoff, backed by President Trump’s endorsement and substantial super PAC spending. Democrat Annie Andrews, a pediatrician, won her party’s primary earlier but faces structural headwinds in a state where Republicans have held both Senate seats for decades. The recent resolution of the Republican nomination contest has further clarified the matchup without altering the state’s underlying partisan dynamics.
