Darline Graham won the South Carolina Republican Senate runoff election on Tuesday after receiving crucial backing from President Donald Trump.
Graham, the adopted sister of the late Senator Lindsey Graham, defeated Congressman Ralph Norman, who had positioned himself as the authentic and experienced conservative in the race. NBC News called the contest just before 9 pm Eastern.
The victory came despite serious doubts raised by home-state Republicans following a series of damaging campaign gaffes during the final week of the race.
Norman conceded defeat to Graham shortly after the race was called, while making clear he was far from pleased with President Trump's intervention.
"His policies are good. I never understood why he got in this race," Norman said of Trump's involvement on Graham's behalf. "It is what it is. I'll accept it."
Norman also acknowledged that Democrats had achieved what they wanted from the outcome. "I accept it. I don't like it, but I accept it," Norman added, promising to support Graham as best he can despite his disappointment.

Trump Rallying Support
Trump drove Graham's campaign forward with heavy personal involvement, encouraging her to enter the race shortly after the death of her brother and deploying his political machine in the final stretch before the runoff.
Appearing in Myrtle Beach on Friday, Trump made a direct plea to his supporters to turn out for Graham, telling them to vote as though he himself were on the ballot. "What I really want you to do is pretend, please, that I'm on the ballot. Just come and vote. It's so important," Trump told rally goers in South Carolina on August 21.
That effort provided Graham with her biggest advantage over Norman, leading to a decisive victory in Horry County, where Myrtle Beach resides.
MAGA Inc., the Trump-aligned super PAC, spent more than $827,000 backing her campaign. Trump also hosted a second tele-rally for Graham on Monday night to drive supporters to the polls.
"I love her," Trump told supporters. "I asked her to do it. I got her into this whole thing. I have to make sure she gets in because there will be nobody better."

Gaffes and Debate Fallout
Despite her win, Graham's campaign was rocked by a brutal debate performance that handed Norman an instant line of attack in a race where he repeatedly argued South Carolina needed an experienced senator with foreign policy expertise.
During the televised debate, Graham was asked about security interests involving Taiwan and the South China Sea. "I'm just gonna be honest here. I'm not on national security, I'm not that informed on national security, so... But I do support the military," she admitted.
The admission exploded online. Norman seized on the opportunity to call out Graham on her lack of security knowledge, writing on X that the state "deserves a candidate who understands foreign policy." He added in a post, "South Carolina deserves a Senator who understands Foreign Policy. I'm a peace through strength supporter! No more forever wars!"

The debate stumble was not Graham's only misstep. She also claimed during the broadcast that 50 million people in South Carolina were living paycheck to paycheck, despite the state having a population of roughly 5.5 million.
Norman pounced on the figure on X, writing, "If we're going to talk about the affordability crisis in our state, we should start by knowing that South Carolina has Checks Notes 5.5 million people." Former Representative Adam Morgan also joined the criticism, posting, "She thinks 50 million people live in South Carolina?"
General Election Matchup
Prior to the debate, Senator Tim Scott backed Graham's candidacy. "I wanted to do so with confidence," Scott wrote a week before the debate. "After watching Darline Graham in the Senate and on the campaign trail, I'm confident she's the real deal."
Norman remained competitive by winning a cluster of northwestern counties around Greenville, but the power of Trump's endorsement ultimately outweighed voter concerns about Graham and her thin public service experience.
Graham now enters the general election as the strong favorite against Democratic nominee Annie Andrews, a pediatrician.
Andrews addressed Graham's victory on X with a photo opposite Graham titled "The sister vs. the doctor," writing, "The field is set and I'm ready to bring this election home."
