South Carolina's U.S. Senate race is trending this week because the Republican side of the contest has just been settled. Senator Darline Graham won a GOP primary runoff on August 25, 2026, defeating Representative Ralph Norman, and will now face Democratic nominee Dr. Annie Andrews in the November general election to fill the remainder of the late Senator Lindsey Graham's term.
Why there's a special election
This race exists because Lindsey Graham, the longtime Republican senator from South Carolina, died in office in mid-2026. Under South Carolina's succession process, his sister, Darline Graham, was appointed and sworn in to serve out part of his term in July 2026. Because the seat became vacant partway through a term, state law requires a special election this year so voters can choose who holds it going forward, rather than waiting for the seat's next regularly scheduled election.
The candidates
On the Republican side, Darline Graham entered the race as the appointed incumbent and faced a competitive primary that included Representative Ralph Norman. Neither candidate cleared the threshold needed to win outright in the first round, which sent the race to a runoff. That runoff, held August 25, 2026, was won by Graham, according to projections from multiple outlets including NBC News, CBS News, ABC News and NPR.
On the Democratic side, Dr. Annie Andrews, a pediatrician from Charleston, won her party's primary in June 2026, advancing past other Democratic contenders to secure the nomination. Andrews previously ran for South Carolina's 1st Congressional District in 2022. If elected, she would be the state's first Democratic U.S. senator in years, a fact that has drawn national attention to a state Republicans have carried reliably in recent statewide races.
What's at stake
South Carolina hasn't elected a Democrat to the U.S. Senate in decades, and the seat has been closely associated with the Graham family, making the family name itself part of the story. Beyond the personalities involved, the outcome will determine who represents South Carolina in the Senate for the remainder of the term tied to this vacancy, at a moment when control of the closely divided chamber is a factor in national political coverage. National party committees and outside groups on both sides are expected to pay close attention to a race that, in a typical year, might not be considered highly competitive.
Timeline
The sequence so far: Lindsey Graham's death created the vacancy in mid-2026; Darline Graham was appointed and sworn in that July; primary elections were held for both parties, with Andrews winning the Democratic nomination outright in June; the Republican primary went to a runoff between Graham and Norman after no candidate won a majority; and that runoff concluded on August 25, 2026, with Graham declared the winner. The general election between Graham and Andrews is scheduled for this November, and further details on turnout expectations and campaign developments are likely to emerge as that date approaches.
As with any fast-moving special election, some specifics — including the exact November election date locally and any additional candidates who may appear on the general-election ballot — were not fully confirmed at the time of writing, and voters should consult official South Carolina election authorities for the most current details.
