Sen. Darline Graham and Rep. Ralph Norman have advanced to a Republican runoff election for a U.S. Senate seat in South Carolina [1].
The runoff determines who will represent the state in a seat that carries a six-year term [2]. The vacancy was created following the death of Sen. Lindsey Graham in July 2026 [3].
South Carolina election rules trigger a runoff when no candidate secures a majority in the initial special primary [1]. Both Graham and Norman emerged as the top candidates in the primary held earlier this month [4].
Sen. Darline Graham currently serves as the appointed interim U.S. Senator [1]. She is the sister of the late Sen. Lindsey Graham [3]. Regarding her campaign to keep the seat, Graham said, "I have to earn voters" [5].
Rep. Ralph Norman (R-SC) will challenge Graham in the runoff [1]. The contest focuses on the Republican base in South Carolina as the party seeks a permanent replacement for the late senator [4].
The runoff election is scheduled for Aug. 25, 2026 [1]. The winner of this GOP contest will move forward to secure the seat [1].
“"I have to earn voters."”
The runoff represents a critical juncture for the South Carolina GOP, pitting an appointed interim senator with a recognized political name against an established U.S. Representative. Because the seat is a six-year term, the outcome will influence the state's federal representation and the party's ideological direction in the Senate for several years.
