Darline Graham won South Carolina’s Republican Senate runoff on Tuesday, defeating U.S. Rep. Ralph Norman and securing the GOP nomination to fill her late brother Lindsey Graham’s seat in the November general election. Graham, 62, captured 52.5 percent of the vote to Norman’s 47.6 percent, according to election results.
Graham was appointed to the Senate on July 14, 2026, by South Carolina Gov. Henry McMaster to fill the vacancy created by her brother’s death on July 11 from an aorta tear at age 71. Because the vacancy occurred more than 100 days before the November election, state law required a special primary to determine the GOP nominee, with a runoff mandated when no candidate won a majority in the August 11 primary.
Graham placed first in that initial primary with 32.75 percent of the vote, but fell short of the majority threshold needed to avoid a runoff. Norman, a U.S. representative from South Carolina’s 5th District, finished second with 24.62 percent, advancing him to the Tuesday runoff.

The runoff tested President Trump’s political influence in the state. Trump recruited Graham to run and publicly backed her candidacy, while opposing Norman’s bid. According to reporting on the final day of the campaign, pro-Trump groups spent $827,000 to support Graham in the runoff’s closing hours.
Graham’s path to the Senate has been unconventional. She spent nearly 30 years in state government focused on disability and workforce issues, serving as a vocational rehabilitation counselor, a commissioner with the South Carolina Commission for the Blind, and in roles with Clemson University and the South Carolina Department of Employment and Workforce. She had never run for or held elected office before her appointment.
During the runoff campaign, Graham acknowledged her lack of legislative experience. In a debate earlier this month, she stated, “I’m not that informed on national security,” though she pointed to her three decades of public service as evidence of her qualifications to serve. Norman, by contrast, has represented his district in Congress since 2019.

Graham’s victory in the runoff advances her to the November general election, where she will face Democratic nominee Annie Andrews, a pediatrician from Charleston. No Democrat has won a South Carolina Senate race since 1998, making the seat heavily favored to remain in Republican hands. A separate link on internal races notes that the South Carolina Senate runoff between Graham and Norman was set for Tuesday, and prior debate coverage shows how Graham and Norman clashed in their runoff debate on national security and other issues.
