The Matt Mahan governor campaign is facing new pressure after a pro-Mahan committee shut down, a major donor refund surfaced and recent polling showed the San Jose mayor trailing key rivals ahead of California’s top-two primary on Tuesday, June 2, 2026.
The developments have raised questions about whether Mahan’s early Silicon Valley-backed momentum can turn into broader voter support in the final stretch of the California governor race.
Matt Mahan Governor Campaign Faces PAC and Donor Questions
An outside committee created to support Mahan has filed papers to close, while California Back to Basics, another pro-Mahan group, returned a $1 million donation from Netflix co-founder Reed Hastings, according to recent reports. The timing has added scrutiny to Mahan’s fundraising strength and outside support.
Political consultant Steven Maviglio said it is “never a good sign” when a donor seeks money back or a committee shuts down. Mahan’s campaign did not respond to questions in the original report about the committee closure or the latest ethics allegations.
Ethics Complaint Adds Another Challenge
The campaign is also facing an ethics complaint filed with the California Fair Political Practices Commission. The complaint alleges that Mahan’s campaign illegally coordinated with California Back to Basics, an outside committee supporting his run.
The allegations have not been proven. If violations are established, the complaint says the campaign could face penalties of up to $5 million.
California Governor Race Polls Show Mahan Behind
A California Democratic Party tracking survey released on Tuesday, May 19, 2026, showed Mahan at 4% support among likely voters. Republican Steve Hilton led with 22%, followed by Democrat Xavier Becerra at 21%, Tom Steyer at 15%, Chad Bianco at 10% and Katie Porter at 7%.
Under California’s top-two primary system, the two candidates with the most votes advance to the November general election, regardless of party. That makes late momentum especially important in a crowded race.
Why It Matters
Mahan entered the governor race in January after positioning himself as a critic of Gov. Gavin Newsom on public safety and state political issues. His launch attracted major Silicon Valley attention, large donations, a Super Bowl campaign ad, a national television appearance and an endorsement from musician Grimes.
But the PAC closure, donor refund, ethics complaint and weak polling now create a difficult closing stretch. For Mahan, the central question is whether financial support and tech-world visibility can translate into enough statewide voter support before the June 2 primary.
