Darline Graham won the Republican primary runoff on Tuesday to become the GOP nominee for a U.S. Senate seat in South Carolina [2].
The victory ensures that the seat formerly held by her brother remains within the family and maintains the Republican party's hold on the nomination heading into the general election.
Graham secured the nomination following a runoff election held on Aug. 25, 2026 [2]. The seat became vacant following the death of her brother, former Senator Lindsey Graham, who died at age 71 [1].
Throughout the campaign, Graham received the endorsement of former President Donald Trump [1]. This support provided a significant advantage in the primary process, helping her navigate the runoff against her Republican opponents.
South Carolina voters now move toward the November general election with Graham as the official GOP candidate. The primary process was necessitated by the sudden vacancy left by the former senator's death, an event that reshaped the state's political landscape this year.
Graham's victory marks a transition of political influence in the state. By winning the runoff, she has positioned herself as the primary challenger for the seat in the upcoming general election, carrying both the party's official nomination and the backing of the former president.
