In California’s increasingly crowded and unpredictable race for governor, billionaire investor-turned-activist Tom Steyer has emerged as the campaign’s most dominant financial force—flooding the state’s airwaves with a level of spending that has both amplified his visibility and intensified scrutiny from rivals.
Backed by his personal fortune, Steyer has launched an aggressive, multi-platform advertising push, saturating television, radio, and digital channels across key markets like Los Angeles. According to data from AdImpact, his campaign has already committed more than $115 million to advertising—nearly 30 times the spend of his closest Democratic competitor. The scale of that investment has drawn sharp criticism, with opponents arguing that Steyer is attempting to leverage wealth to secure California’s highest office.
“If billionaire money is flooding our state,” warned Katie Porter, one of Steyer’s principal challengers, “it’s in an attempt to buy this election.”
Yet despite the overwhelming financial advantage, Steyer has not decisively separated himself in the polls. As California approaches its June 2 primary—where only the top two candidates, regardless of party, advance to the general election—the race remains unusually fluid. A recent survey by the Public Policy Institute of California placed Steyer in a tight cluster alongside Porter, Republican contenders Steve Hilton and Chad Bianco, and former congressman Eric Swalwell prior to his abrupt exit from the race.
Swalwell’s withdrawal—following allegations he denies—has further reshaped an already unsettled contest, while Donald Trump’s endorsement of Hilton has injected additional political tension into the field. Even so, no single candidate has emerged as a clear frontrunner.
Veteran strategist Bill Carrick suggests Steyer’s massive ad spend may be yielding diminishing returns. “If your first round of ads doesn’t move you dramatically, the later rounds won’t either,” he noted, adding that the race appears unusually stagnant. “Somehow, the campaign is frozen.”
History offers cautionary parallels. Wealth has not always translated into electoral success—whether in the case of Rick Caruso’s $100 million mayoral bid in 2022 or Michael Bloomberg’s billion-dollar presidential run in 2020. Steyer himself encountered similar limitations during his own presidential campaign that year, exiting early after failing to gain traction.
Still, his campaign remains optimistic. Spokesperson Kevin Liao recently described Steyer as “the only Democrat with the grassroots energy, institutional backing, and resources to advance,” pointing to key endorsements, including backing from the powerful California Teachers Association.
Steyer’s messaging has centered on economic pressure and immigration policy—two issues dominating voter concerns. In campaign ads, he pledges to reduce the cost of living and has taken a hard stance against federal immigration enforcement, including calls to dismantle U.S. Immigration and Customs Enforcement. “Everybody needs an affordable place to live,” he says in one widely aired spot, underscoring housing affordability as a central pillar of his platform.
As mail-in ballots are set to be distributed, the question looming over the race is whether unprecedented spending can translate into meaningful voter momentum—or whether California’s electorate will once again demonstrate that money, even in vast quantities, cannot buy political destiny.
