Since the South Carolina Republican gubernatorial primary concluded Tuesday evening, the results delivered a blunt verdict on the power of a Trump endorsement in a competitive GOP field.

The Numbers Are Brutal for Mace

Rep. Nancy Mace (R-SC) conceded the race within two hours of polls closing, according to the New York Post. She was pulling just 11.3% of the vote — good for fifth place, not second, not third. Fifth.

Meanwhile, Trump-backed Lt. Gov. Pamela Evette held approximately 29%, and state Attorney General Alan Wilson sat at roughly 26%. Both advance to a runoff to determine the Republican nominee to succeed term-limited Gov. Henry McMaster.

Mace endorsed Wilson in the runoff during her concession speech.

What Trump's Endorsement Actually Did

Trump endorsed Evette on May 29, according to the New York Post — just ten days before the primary. Polling had already shown Evette as the frontrunner before Trump's public blessing, but the endorsement shredded any remaining oxygen for the rest of the field.

Trump's Truth Social post was direct: "She never wavered, never let me down, and was the only South Carolina Gubernatorial Candidate to Endorse me as soon as I launched my 2024 Presidential Campaign."

Evette's first campaign ad back in August 2025 was built around exactly that loyalty claim: "It's good to have President Trump's back. I've backed him from Day One."

The Race Mace Lost Before Election Day

Mace had spent the entire primary trying to out-Trump Evette. Her social media featured Trump's 2024 congressional endorsement prominently. When Trump announced for Evette, Mace posted — in all caps — that "Pamela Evette is NOT ENDORSED by DONALD TRUMP. Do not believe her LIES." That was the same day Trump endorsed Evette.

Mace also argued, according to the New York Post, that her push to release the Epstein files played a role in Trump passing her over. What is confirmed is that Evette was ahead before the endorsement and pulled further ahead after it.

What Mainstream Coverage Is Missing

Most coverage frames this as a "Trump endorsement wins again" narrative, which is accurate but incomplete.

Alan Wilson, the state's Attorney General, finished only three percentage points behind Evette without a Trump endorsement going into the primary. He has a substantive record and a different coalition. The runoff could be genuinely competitive — and if Wilson closes the gap, it complicates the simple "Trump picks, Trump wins" storyline.

Mace's fifth-place finish isn't just about Trump's snub. She's a congresswoman with a statewide profile, a history of viral moments, and years of MAGA-adjacent positioning. Finishing at 11% means her brand — whatever it actually is at this point — didn't translate to votes outside her congressional district.

The Case Against Mace's Position

Mace's supporters argue that Trump endorsements should not automatically go to the most loyal rather than the most qualified candidate. Loyalty to Trump and fitness for governor are different things. Mace had a record in Congress, won a tough 2024 primary, and built a national profile. If the only variable that matters is who hugged Trump first, that's a narrow test for choosing a governor. The concern that Trump's political decisions are influenced by non-policy factors is shared across the party — not just Mace's camp.

What This Means for South Carolina

The Republican nominee will be either Evette or Wilson. South Carolina remains a reliably red state in statewide races — the Democratic nominee faces steep odds in November regardless of who emerges from the runoff.

The runoff dynamic between Evette and Wilson will test whether Trump's endorsement remains the primary currency in state-level GOP primaries, or whether a credible alternative candidate can consolidate around policy and record instead.

Mace's political future remains unclear. Her congressional seat, her national brand, and her relationship with Trump's orbit are all complicated now. Finishing fifth in a statewide primary you entered as an incumbent congresswoman is a difficult result to spin.

The voters made their choice clearly. The runoff now defines what comes next.
