Recent polling from firms including InsiderAdvantage and Trafalgar has shown Republican Sen. Darline Graham and Democratic pediatrician Annie Andrews locked in a statistical tie, with Graham holding nominal leads of 1–2 points among likely voters. This tightness stems from the compressed timeline after Lindsey Graham’s July 2026 death, Darline Graham’s appointment and subsequent primary victory with Trump’s backing, Andrews’ heavy early ad spending on pocketbook and healthcare themes, and persistent undecided voters near 8–9 percent. Upcoming events such as the October 11 debate and final Republican media pushes could shift margins, but current trader consensus on narrow outcomes or an Andrews win reflects the race’s departure from historical Republican dominance in the state.
