South Carolina Republicans are navigating a contested primary for the late Senator Lindsey Graham’s seat following the surprise announcement by his sister, Darline Graham, that she will seek a full term. Her candidacy, backed by President Donald Trump, faces pushback from party members questioning her political experience and the necessity of a primary.
President Donald Trump Endorses Darline Graham for a Full Term
Darline Graham’s Full-Term Bid
Darline Graham was sworn in last week to serve the remainder of her late brother’s term, an act many in the state viewed as a respectful tribute to the senator. Her decision to pursue the seat permanently arrived on Monday after President Trump posted on social media saying he had encouraged her to do so. While the endorsement from the president is intended to provide immediate credibility to a political newcomer, it has triggered a backlash among some local party officials who expected her to serve only as a caretaker until the end of her brother’s term in January.
Her interest in running for a full term even caught South Carolina party brass off-guard. Drew McKissick, chair of the South Carolina Republican Party, told POLITICO Friday he thought Graham told Gov. Henry McMaster she’d accept the appointment to fill the rest of the term, not to be a candidate for it.
Dorchester County GOP Chair CJ Westfall Critiques the Presidential Intervention
Resistance Within the South Carolina GOP
The reception to the endorsement has been notably skeptical in certain party quarters. CJ Westfall, chair of the Dorchester County GOP, noted that while the initial appointment was well-received as a gesture of respect, the entry of the president into the race has complicated the party’s internal dynamics.
Even folks that didn’t like Senator [Lindsey] Graham or didn’t vote for him in the primary were pretty happy about the appointment, as a tribute to Senator Graham,
Westfall said. But once we saw the president jump in and support her, 95 percent are saying, ‘What the hell are we doing here? We don’t know how she votes. We don’t know what she believes.’
A Republican operative unaffiliated with the race, who was granted anonymity to candidly discuss the landscape, noted that the recent loss of Lt. Gov. Pam Evette—who lost her bid for governor despite Trump’s endorsement—has changed the calculus. I think people saw [Trump’s] endorsement of Pam Evette and her terrible performance and know this race could be up for grabs like the gubernatorial was,
the operative said.

Rep. Russell Fry and Rep. Ralph Norman Launch Primary Challenges
The Growing Field of Challengers
The uncertainty surrounding Darline Graham’s candidacy has encouraged a crowded field of Republican challengers. Rep. Russell Fry, described as one of Trump’s most loyal congressional allies, announced earlier Monday he was jumping in. In his launch video, he presented himself as a Trump-aligned “MAGA warrior.” In a statement, Fry campaign spokesperson Luke Byars noted Fry has been honored to receive President Trump’s endorsement
in his previous elections. Our focus for the next three weeks remains ensuring South Carolina has a conservative fighter in the United States Senate who will advance the President’s agenda and deliver real results for South Carolina families,
Byars said.
Fry joins Rep. Ralph Norman, who declared his candidacy over the weekend, and self-funding businessman Mark Lynch, who lost to the former senator in the primary. Other Republicans are mulling runs, including former Gov. Mark Sanford and Lt. Gov. Pam Evette. Norman told reporters on Monday that Trump’s endorsement helps a great deal.
That’s why I ask[ed] him for it,
he added. I’d rather have it, but it’s up to the people.
Senate Majority Leader John Thune Declines to Endorse a Candidate
Senate Leadership Stance
Senate Majority Leader John Thune (R-S.D.) told reporters he won’t endorse a primary candidate. I’m not endorsing at the moment,
Thune said. Thune defended the new Senator Graham’s professional background, noting that she is a very accomplished person in her own right,
citing her work in multiple roles at state agencies and in the private sector helping people with disabilities find jobs. I mean, I think she’s, obviously carries on Lindsey’s legacy,
Thune said.
Primary Timeline and General Election Stakes
The Republican field is racing toward a special primary scheduled for August 11, 2026, with a runoff later in August if needed. The eventual Republican nominee is set to face Dr. Annie Andrews, a Democratic pediatrician, in the November general election.
