President Trump is working the phones to consolidate Republican support behind his endorsed Senate candidate in South Carolina, calling former Gov. Mark Sanford and Rep. Russell Fry to back Darline Graham Nordone ahead of an August 25 runoff.
On primary election night, as Graham Nordone and Rep. Ralph Norman advanced to the runoff, Trump picked up the phone and dialed Sanford, a man he has clashed with for years, and asked him to endorse Graham Nordone. Sanford, who finished fourth in the primary, gave Trump no commitment and later told reporters he did not plan to endorse in the runoff.
Trump also called Fry, who finished third. That call produced results. On Friday, Fry endorsed Graham Nordone in a public statement:
"President Trump needs fighters and allies in the Senate who will show up every day and get results. I believe Darline Graham will be exactly that."
Fry's backing carries geographic weight. Myrtle Beach sits in his congressional district, the same area where the Trump team is now weighing a rally for Graham Nordone before the runoff, three people familiar with the discussions told the Washington Post. The event has not been finalized.
Sanford's history with Trump makes the outreach notable. The former governor broke with Trump years ago, and that split cost him his House primary in 2018. Sanford then challenged Trump for the 2020 Republican presidential nomination. The fact that Trump called him anyway signals how seriously the White House is treating this runoff.
Sanford's refusal to commit leaves him on the sideline. But Trump's willingness to reach across old fault lines, even to a former rival who ran against him, shows a candidate-consolidation effort that goes beyond routine endorsement politics.
Trump endorsed Graham Nordone in July, giving her what Breitbart described as a "complete and total endorsement" for the U.S. Senate race. On primary night, he told reporters plainly: "They're all Trumpers, but, I endorse her. I think she's great."
Graham Nordone's runoff opponent, Rep. Ralph Norman, has assembled his own coalition, and it includes names that carry weight in conservative circles. Sens. Rick Scott of Florida and Mike Lee of Utah have both endorsed Norman. So have Turning Point Action and CPAC.
Norman also has the backing of former South Carolina Gov. Nikki Haley, with whom he shares a long alliance. Norman was one of just two House members to support Haley over Trump in the 2024 presidential primary. A source close to Haley told the Washington Examiner she is "prepared to do whatever it takes to help him win."
That lineup gives Norman institutional conservative backing. But it also positions the runoff as a test of whether Trump's personal endorsement carries more force than a coalition of Senate allies and movement organizations. Trump has shown he takes those tests personally, and he has intervened in similar runoff fights before.
On Thursday, South Carolina Republicans began receiving texts carrying a poll conducted by the firm Dynata. The survey tested how a dual endorsement, Trump backing both Graham Nordone and Norman, would affect their vote. It is unclear who paid for the survey.
The poll's existence points to a live debate inside Trump's orbit. Some Trump allies have floated the idea of a dual endorsement, which would let the president claim credit for whichever candidate wins. Trump has not ruled it out.
But Trump has reason to be cautious about that approach. He issued a dual endorsement in South Carolina's June gubernatorial primary, backing both candidates. His initial pick, Lt. Gov. Pamela Evette, lost the runoff. The episode was a reminder that splitting an endorsement can dilute its power, and leave the president tied to a loser. Trump has shown elsewhere that he is willing to pull endorsements entirely when circumstances shift.
A full rally in the Myrtle Beach area would send a different signal, one that leaves no ambiguity about where Trump stands. Fry's district gives the event a natural base of support, and the congressman's endorsement would let Trump present a unified front with a local ally who just competed in the same primary.
Norman's connection to Haley gives this runoff a dimension beyond a standard intraparty contest. Haley challenged Trump for the 2024 Republican nomination, and Norman's decision to back her over the sitting president marked him as one of the few House Republicans willing to break ranks. That history hangs over the runoff whether Norman wants it to or not.
Trump's endorsement decisions have carried real consequences in recent cycles. In races across the country, his backing has lifted candidates and reshaped primaries, though not always with the outcome he wanted. The Arizona GOP primary earlier this cycle showed that his endorsement can push a candidate through even under difficult circumstances.
For Graham Nordone, the calculus is straightforward: Trump's endorsement, Fry's backing, and a potential Myrtle Beach rally give her the machinery to consolidate the primary field's voters behind her candidacy. For Norman, the question is whether the Scott-Lee-Haley-Turning Point coalition can match that in a low-turnout runoff.
The August 25 runoff will test something Republicans keep debating: whether Trump's direct involvement in down-ballot races strengthens the party or simply reshuffles its internal loyalties. In South Carolina, the answer will come with a Senate seat attached.
Trump has also shown he is not afraid to cross party lines to reshape a race when he sees an opening, and this runoff gives him one more chance to prove that his word still moves Republican voters where it counts.
When the president of the United States picks up the phone on election night and starts dialing former rivals, it is not a courtesy call. It is a reminder that in today's Republican Party, endorsements are not suggestions, they are marching orders.
