Thrown into office and an unexpected campaign, Darline Graham is running on her brother’s legacy—but making clear that she’s different.

August 25, 2026, 6 AM ET Share Save It’s something that happens so often in politics that there’s a name for it: widow’s succession. Dozens of times over the past century, women have filled a seat previously occupied by their late husband, and some have gone on to serve a long career.
What has never happened in Congress before is what Darline Graham is doing: a sister’s succession.
Less than 48 hours after Senator Lindsey Graham died suddenly from heart issues last month, South Carolina Governor Henry McMaster appointed Graham’s younger sister to complete the remaining six months of his term. Soon after that, Darline Graham announced that she would also run for a full six-year term, a bid that came at President Trump’s request. In the solidly red state, her biggest hurdle is likely to come in a primary runoff today. She is running in part on the legacy of her brother—but also in ways that bear no resemblance to the way he approached the job. Where he was chatty and seemed to love campaigning, she is reserved and describes the campaign as “brutal.” Where he was the ultimate Washington insider who served in Congress for more than 31 years, she is running as a populist outsider who previously worked with the disabled and visually impaired. And where he was one of his party’s most prominent and outspoken foreign-policy hawks until the day he died, she has conceded to having no experience and not much interest in such matters.
“I’m not that informed on national security,” she said during a debate last week, a blunder that has become a focal point in the final days of an abbreviated campaign. The president came to her defense, praising her for being honest. He has invested significant time and political capital in attempting to give her a late boost in a closer-than-expected primary race.
Her late brother comes up during almost every public event she holds—“I knew I could not sit on the sidelines. That’s not how Lindsey and I were raised,” she’s said—and campaign mailers tout that she is “Prepared to Carry on Lindsey’s Legacy.” She tells voters that “no one can ever fill his shoes” but that she will earn his seat. “I don’t just expect it to be handed to me,” she said earlier this month after casting her ballot in the special primary election.
Her Republican primary opponent is Ralph Norman, a congressman since 2017 who earlier this summer lost his bid for governor. He has also referenced Lindsey Graham’s pull on the race. “Nobody’s entitled by birthright to this office,” Norman said before the debate last week. “You’ve got to earn it.” He tried to put the situation into college-football terms during an interview with the Associated Press, telling voters to imagine presenting the head coach at Clemson University with a top quarterback prospect who has just this qualification: They’re kin to Tom Brady. “Tell me how that analogy doesn’t work here,” Norman said. Although Graham has a famous last name and the president’s endorsement, Norman and his supporters believe that he can win today. Their message: Darline Graham is not Lindsey Graham. A PAC supporting Norman recently began running an ad that asks, “What if Darline Graham had any other last name?”
It’s the last name that has gotten her here—the reason she was appointed interim senator. But in the final stretch of the race, it is complicating her campaign, which has become the latest test of the power of Trump’s endorsement. Although the president has often played kingmaker in Republican primaries over the past decade, that influence has significantly weakened: 10 of his picks have failed to advance this year, many of them in the past few weeks. The congressional candidates Cory Mills and Catalina Lauf both lost in Florida last week. Two of his picks in races for governor—Megan Degenfelder in Wyoming and Mike Lindell in Minnesota—lost by double digits. If Graham loses, it will signal a limit to Trump’s ability to direct the MAGA base in one of the most MAGA states.
T he relationship between Lindsey and Darline was long ago condensed into a few stock lines in their stump speeches: how they grew up in a one-room home that was attached to the bar and restaurant their parents ran. How their parents both died when Lindsey was in college, and how he took responsibility for helping raise his sister, who was nine years his junior. “Lindsey has been there for me throughout the years,” she said at the Iowa State Fair during his long-shot 2016 presidential campaign. “He has never let me down since then. He’s always been by my side.” Her remarks were earnest. And then he jumped to the stage with a joke: “Well, as Darline said, we grew up in a pool hall, a bar, and a liquor store. I’m eminently qualified to be president of the United States!”
A more textured version of their relationship emerges in a memoir he released during that campaign. He tells of how he arranged for her to have golf lessons, so that she could play one of his favorite sports. He took her to the movies (they both loved James Bond). He taught her to ride a bicycle when she was 5—then gifted her a turquoise one when she turned 9. In the early 1970s, he wrote, he heard his young sister use a racial slur. “She didn’t even think the term was offensive. She had heard it used so often,” he wrote. “I told her to not say it again, and a little while later, I went to my parents and asked them to make a change.” Graham says his mother offered a beer to a Black customer, who previously would have taken his beer home, and motioned to him to take a stool, slowly beginning to more actively integrate the barroom.
Graham also wrote of persuading his parents to take Darline to Disney World, a trip that became their first big family vacation. (Years later, in March 2026,…
