California Republicans head into a pivotal convention this weekend with a clear choice on who should lead their ticket for governor, and President Trump has already put his weight behind one contender. The endorsement has stirred energy, anxiety, and arguments about whether a GOP candidate can break through in a state that has not elected a Republican statewide in decades.
Delegates will gather in San Diego to settle an endorsement that could shape the primary. The California GOP wants unity, momentum, and a nominee who can challenge the status quo in Sacramento, and endorsements at the convention often swing that momentum fast.
President Trump threw his support behind one candidate last week, arguing that California had “gone to hell” and that “Steve can turn it around, before it is too late, and, as President, I will help him to do so!” That kind of backing from the former president carries weight with the party base and can quickly change the landscape among delegates.
California Republican Party chairwoman Corrin Rankin said bluntly, “I think it definitely can help rally the base behind a candidate and generate some noise and some enthusiasm,” and delegates will now judge whether that noise becomes votes. In a state where Republicans are desperate to build momentum, rallying the base matters more than ever at a convention where 60% support is needed for an official endorsement.
Riverside County Sheriff Chad Bianco has deep ties inside conservative circles and is seen as a loyal Trump ally by many activists. He has also been unapologetic about taking bold actions that grabbed national attention, and he answered the president’s endorsement with defiance rather than retreat.
Bianco told supporters in a social media video, “For too long, politicians and insiders from Sacramento to Washington have tried to pick our leaders for us. That’s not leadership, that’s a coronation, and it’s exactly how we ended up with the failed leadership Californians are living with today,” and he added, “This election belongs to the people, not the political class.” He wants the base to see his campaign as the authentic street-level conservative option.
Steve Hilton, the other major GOP contender, comes with a different profile: a media figure and former adviser to a British prime minister who only became an American citizen in 2021. For many conservative activists his outsider status is exactly the point, and Trump’s stamp of approval is likely to translate into stronger convention support and fresh fundraising interest.
Still, there are practical consequences to watch. California’s top-two primary system puts every candidate on the same ballot, making it easy for a crowded field to produce two Democrats in November. Some on the right privately admitted they hoped for an R-vs-R runoff, but that outcome never looked likely in a deep-blue state when Democratic turnout is high.
As one political observer put it, “Trump kills any GOP hopes of an R vs R runoff in the California governor’s race,” and campaign strategists are recalculating where every vote could matter. If Trump’s endorsement consolidates conservative voters behind one GOP name in the primary, it might boost chances at getting a Republican into the top two, but it could also widen intraparty divisions if it alienates other factions.
Hilton pushed back on fantasies about shutting Democrats out, saying, “That scenario of two Republicans [making the general election ballot], I’ve been saying this for months, was always a fantasy,” Hilton said on Fox Business’ “The Bottom Line.” “The idea that the Democrat machine in California was just going to hand over the state to two Republicans was never serious. It was never, never going to happen.”
He doubled down on his argument about realistic paths forward: “What was more likely was actually…you were going to have two Democrats in the top two and then we’ll have no chance of change. So this really makes sure that we have a Republican in the top two.” That line speaks directly to the GOP’s central concern: simply being in the fight come November.
No Republican has won statewide in California since Arnold Schwarzenegger in 2006, and that historical fact haunts every campaign strategy discussion. Add the reality that President Trump’s approval in the state hovers in the 30s, and conservatives must weigh whether a high-profile endorsement helps secure November or handicaps a nominee in a general election.
