The political landscape feels different this summer. The air isn’t just hot; it’s thick with a lingering question. Everyone is asking it, from donors in D.C. to volunteers knocking on doors in Myrtle Beach. How much weight does a Trump endorsement really carry now? We are about to get a very clear answer.
This Tuesday, voters in South Carolina and Oklahoma head to the polls for runoff elections. The outcomes will test the former president’s core political power. His ability to hand-pick nominees is directly on the line. In South Carolina, he backs Darline Graham for Senate. In Oklahoma, he supports Mike Mazzei for governor. A win in either contest would let Trump claim his influence is undimmed. A loss in both would signal a palpable shift within the GOP electorate.
“We need every South Carolina patriot to go to the polls and vote for Darline Graham,” Trump urged at a rally last week. His plea was revealing. “What I really want you to do is pretend, please, that I’m on the ballot.” That statement cuts to the heart of the matter. Trump isn’t just endorsing candidates. He is asking voters to make the race a proxy for their loyalty to him. It is a high-risk strategy that acknowledges his endorsement alone may not be enough.
The South Carolina Senate runoff is particularly fraught. Darline Graham is running to succeed her late brother, Senator Lindsey Graham. She has the full force of the state’s establishment behind her. Governor Henry McMaster appointed her to the seat. She is backed by Trump ally Rep. Russell Fry and Senator Tim Scott. Yet she faces a formidable challenger in conservative Rep. Ralph Norman.
Norman represents the complicated strands of modern Republican politics. He is a staunch conservative who showcases his support for Trump’s policies. However, he was the only South Carolina congressman to endorse Nikki Haley over Trump in the presidential primary. Now, he is backed by former Governor Mark Sanford. “Trump still has a nasty taste in his mouth for Nikki Haley,” a state Republican strategist told me, requesting anonymity to speak candidly. This race isn’t just policy. It is deeply personal for Trump.
Recent history in the state should give the Trump camp pause. Just last month, his endorsed candidate for governor, Lt. Gov. Pamela Evette, lost her runoff in a landslide. Trump ended up endorsing her opponent too, days before the vote. It was a stark scramble for victory. The same strategist framed Tuesday’s vote bluntly. “It’s becoming a referendum on Trump. He came to South Carolina to solidify his endorsement because he has to show a win here.”
The dynamic in Oklahoma’s gubernatorial runoff is less personal but equally consequential. Trump-backed Mike Mazzei finished slightly behind state Attorney General Gentner Drummond in the first round. Oklahoma is a deeply red state. The winner of this GOP runoff will be the overwhelming favorite in November. A loss for Mazzei here would mark another high-profile setback for Trump’s kingmaking.
His overall record this cycle is mixed, a nuance often lost in the headlines. Trump boasts a powerful endorsement scorecard. “My Endorsements are stronger than ever,” he posted on social media. Yet five of his gubernatorial picks have lost their primaries. This list includes candidates in:
- Georgia
- Iowa
- Wyoming
- Minnesota
- Florida
- Texas
Each loss had its own local reasons, but the pattern is undeniable.
“There’s no question that an endorsement from President Trump provides a tremendous boost in a Republican primary. But it doesn’t necessarily mean the candidate’s going to win,” veteran GOP strategist Ryan Williams noted. He explained that while Trump maintains a firm grip on the party, underlying candidate weaknesses can be fatal. “If there are issues with a candidacy, those can pose problems that even an endorsement can’t overcome.”
Meanwhile, in Georgia, a special election runoff will fill the remainder of the late Rep. David Scott’s term. The two candidates are Democrats. The winner will further shrink the House GOP’s fragile majority. This contest is a stark reminder that while Republicans fight internal battles, the broader political consequences are very real.
As I watch these races unfold, the broader narrative comes into focus. Trump’s influence is not an off/off switch. It is a dial. It can amplify a candidate’s message and mobilize his core base. But it cannot magically erase a candidate’s flaws, overcome local grievances, or quell a rebellion from other conservative factions. The era of the automatic Trump primary win is over.
Tuesday’s results will tell us exactly where that dial is set. A clean sweep for Trump-backed candidates would reset the narrative of his invincibility in primaries. Split decisions or losses will confirm a new, more complicated phase. In this phase, his endorsement is a powerful weapon, but not the only one that matters. The GOP is still Trump’s party. The voters, however, are starting to remind everyone they have a mind of their own.
