Darline Graham Nordone holds an 87% implied probability in the Greenville County portion of South Carolina’s U.S. Senate race, reflecting the county’s longstanding Republican dominance and her status as the party nominee. Appointed to the seat after Lindsey Graham’s July 2026 death and confirmed via August special primary runoff with strong party support, she benefits from early voting patterns and voter registration advantages in the Upstate region. Statewide polls show a narrower contest against Democrat Annie Andrews, yet county-level results historically deliver larger Republican margins. Minor candidates and “other” options trade near 50%, underscoring limited expected impact on the outcome before November 3.
