San Diego’s Republican convention was supposed to be a confidence-builder. It didn’t stay that way for long.
The California GOP arrived with a story it could actually sell: two credible gubernatorial candidates, former Fox News host Steve Hilton and Riverside County Sheriff Chad Bianco, were both polling well enough that party strategists believed they could squeeze Democrats out of the top-two primary system results altogether. That scenario, a Republican vs. Republican November final, hasn’t happened in a California statewide race in roughly two decades. It was a stretch. It wasn’t delusional.
Then President Donald Trump endorsed Hilton, and that’s when things got complicated.
“He screwed over California Republicans yet again,” said Rob Stutzman, a Republican political consultant who’s been vocal about the party’s strategic missteps. “It’s just political malpractice to not have done a dual endorsement. People were briefing the White House on the situation.”
The endorsement landed at a rough moment. California Republicans were already sorting through the aftermath of last November’s Proposition 50 fight, a Democratic-drawn gerrymandering measure designed specifically to push five Republican members out of Congress ahead of the midterms. The party lost that one. It hurt. What made the wound deeper was the ongoing absence of Kevin McCarthy, the Bakersfield congressman who served as House Speaker and spent years making sure Washington’s Republican establishment didn’t forget California existed. That institutional connection is largely gone now.
So the 2026 governor’s race, along with a short list of competitive legislative seats where the party has held seats against the odds, had become the clearest argument California Republicans could make for their own relevance. Trump’s move into that space scrambled the math.
Winning statewide in California isn’t a base game. It can’t be. The state’s electorate is too large, too diverse, and too Democratic for any Republican to survive the general by turning out core supporters alone. Trump lost California by more than 20 points in 2024. That’s not a rounding error. Some Republican candidates running in competitive districts have actually used their distance from Trump as a pitch to moderate voters. His endorsement, in certain California races, is closer to a liability than an asset.
“The big fight if you’re trying to be elected governor is actually to have a broad-based appeal in California,” said Matt Rexroad, a Republican campaign consultant who previously worked for Bianco. “President Trump doesn’t provide that.”
Bianco isn’t dropping out. He’s been has been tracking the convention’s buildup closely, and his team came in knowing the delegate fight would be difficult. To earn the state party’s official endorsement, a candidate needs 60% of delegate votes. That threshold was already steep before Trump weighed in. It’s steeper now. Bianco did get attention recently for seizing hundreds of thousands of ballots over voter fraud allegations, a move that fired up his base but drew sharp criticism from those who called it a serious overreach of his authority as sheriff.
The convention dynamic now is essentially a test of whether Trump’s national weight can translate inside a California party meeting in a way that it demonstrably doesn’t translate in a California general election. Hilton has the endorsement of the most powerful Republican in the country. Bianco has a following among the party’s most committed activists and a recent headline that kept him in the conversation even if it also made him a polarizing figure outside the GOP base.
What the weekend made clear is that the Republican scenario everyone was quietly hoping for, two viable candidates in a general election with no Democrat on the ballot, got harder the moment Trump picked a side. The party’s best-case math required keeping both candidates viable. A presidential endorsement of one of them doesn’t do that.
Stutzman, who’s worked Republican campaigns in California for years, didn’t soften his read on the situation. The White House was told what was at stake for California Republicans heading into 2026. They chose Hilton anyway.
