South Carolina’s strong Republican lean, demonstrated by consistent statewide victories and a 2024 presidential margin exceeding 17 points, underpins trader consensus favoring Darline Graham Nordone. Appointed to the Senate in July 2026 after Lindsey Graham’s death, she secured the Republican nomination in an August 25 special primary runoff against Rep. Ralph Norman, aided by President Trump’s endorsement and campaign resources. Democratic nominee Annie Andrews, a pediatrician who won her primary outright, faces structural headwinds in a state where no Democrat has won a Senate seat since 1998. With the November 3 general election approaching, recent polling averages show Graham ahead by roughly 8 points, aligning with the market’s implied probabilities and historical patterns for open or appointed Republican seats in the Palmetto State.
