Darline Graham was projected Tuesday night to win the Republican runoff in South Carolina, a victory that gives her the GOP nomination spot on the ballot for the Senate seat long occupied by her late brother, Sen. Lindsey Graham.
Swift contest follows sudden vacancy
The contest followed the unexpected death of Lindsey Graham, a four-term senator who had been seeking re-election. His passing set off a rapid scramble in the state to determine who would both fill his unexpired term and appear on the ballot this fall for a full six-year term.
Gov. Henry McMaster appointed Darline Graham to serve the remainder of her brother’s term, which runs through early next year. But the question of who would be listed as the Republican nominee for the full term was left to voters after Lindsey Graham — who had won the GOP primary in June — died.
Runoff outcome and campaign dynamics
CBS News projected Darline Graham defeated Rep. Ralph Norman in the special primary runoff on Tuesday night. The two had been the top finishers in the Aug. 11 special primary; neither reached the 50% threshold needed to avoid a runoff, leaving the decision to a head-to-head contest.
In the initial special primary, Darline Graham received nearly 33% of the vote, while Norman received almost 25%. The runoff therefore became a test of whether Graham could expand her plurality into a majority.
| Candidate | Aug. 11 special primary | Runoff result |
|---|---|---|
| Darline Graham | Nearly 33% | Projected winner |
| Ralph Norman | Almost 25% | Defeated |
Profile and message
At 62, Darline Graham entered the contest with no prior elected office experience but with decades of public service in state roles, most recently as commissioner of the South Carolina Commission for the Blind. She emphasized her work history in South Carolina and framed herself as someone who could handle the responsibilities of a full Senate term.
Her campaign highlighted a close relationship with her brother — who never married or had children — and she presented herself as intent on carrying forward his legacy while also advancing her own style of leadership. The campaign leaned on endorsements, including encouragement from former President Donald Trump for her to run, though other Republican figures, including Norman, also sought the nomination.
"I am a problem solver, a critical thinker, and a leader,"
Graham used those descriptions in campaign appearances as she sought to reassure voters about her readiness for the Senate despite lacking prior experience holding elective office.
Policy focus and moments from the campaign
Throughout the short, high-profile contest, questions about foreign policy emerged as a point of focus. In one debate moment noted during the campaign, Graham stumbled when answering a question related to Taiwan and the South China Sea — a moment that drew attention as she asked voters to weigh experience against temperament and commitment.
Her campaign repeatedly stressed service to the state and a work ethic she attributed to the family background: both she and her brother came from parents who ran a bar and a liquor store in central South Carolina, a detail Graham cited to explain their approach to work and public life.
What’s next
With the runoff projected in her favor, Darline Graham will be the Republican nominee on the ballot in November as the party seeks to retain a seat that has been in her family for years. She currently serves in the seat by gubernatorial appointment until the term ends early next year.
- Graham was appointed to finish her brother’s term after his sudden death.
- The Aug. 11 special primary forced a runoff because no candidate reached 50%.
- President Trump publicly encouraged Graham to pursue the full term.
Republican voters in South Carolina will now turn their attention to the general election matchup this fall, where the outcome will affect the balance of power in the Senate and reflect how voters respond to a high-profile intra-party succession that unfolded under unusual and sudden circumstances.
