Darline Graham Wins GOP Senate Runoff in South Carolina After Trump-Backed Campaign

Sen. Darline Graham, sister of the late Sen. Lindsey Graham of South Carolina, won the Republican nomination for U.S. Senate on August 25, 2026, defeating Rep. Ralph Norman in a special election primary runoff. The seat became open following Lindsey Graham's death, and Graham, a political newcomer, sought to fill the remainder of his term. The initial special election primary occurred around August 11-12, 2026, with Graham finishing as the top vote-getter and Norman as runner-up, triggering the runoff since neither secured a majority. President Trump endorsed Graham and campaigned for her, including appearing at a rally in South Carolina on or around August 21-22, 2026. Rep. Russell Fry endorsed Graham on August 14, 2026, after his own primary bid ended, urging his supporters to back her. Conversely, Mark Lynch endorsed Norman around the same time, on August 14, 2026. Graham campaigned on her closeness to Trump, while Norman emphasized his conservative record. During his South Carolina rally, Trump made remarks describing the Strait of Hormuz as "American territory" amid an ongoing U.S. military posture toward Iran, a comment reported alongside the campaign coverage but not central to the Senate race itself. Graham's victory in the runoff was characterized by some outlets as a significant win for Trump, who had "gone all in" backing her candidacy. Reports differed on the state of her campaign heading into the runoff, with one account describing "emerging cracks" and Trump's rally as an effort to shore up support, while others did not characterize the campaign as struggling. Graham will now proceed to the general election in November to compete for the seat permanently; specific general election opponents and the full implications of the Hormuz remarks remain outside the scope of confirmed reporting tied to this race.
