With the June 2 primary on Tuesday, a surge of big-money spending has turned California State Senate District 10 into a high-stakes brawl between tech-aligned interests and labor-backed forces. Outside committees and corporate political arms have rushed in during the final stretch, blanketing parts of Alameda and Santa Clara counties with mailers, TV spots and targeted digital ads. The spending blitz has pulled a normally local race into the spotlight and stirred fresh questions about how much outside influence voters are willing to tolerate.
Outside Groups Push Heavy Spending
Outside spending has jumped sharply in the run-up to the primary, with business-aligned PACs and tech-friendly committees placing big advertising buys to lift some candidates and bruise others, according to The Mercury News. That reporting describes tech donors and corporate PACs treating the contest as a proxy fight over regulation and business policy rather than a quiet local legislative race. Voters are now watching a national-style ad war play out on their own streets.
Where The Money Is Coming From
Campaign-finance filings compiled by The Ballot Book show Uber's political arm funding television buys topping $1 million in support of Union City councilmember Scott Sakakihara. A Meta-linked committee has put about $966,000 into mailers and digital placements. The same data show pro-business groups such as Grow California dropping seven-figure sums on Sakakihara's behalf, while business-aligned PACs have spent roughly $550,000 to oppose West Valley-Mission Community College trustee Anne Kepner.
According to those filings, Sakakihara has received more than $3 million in support overall, including a $1 million campaign loan and a $250,000 late self-contribution reported in May. On the other side, labor and nurses' committees have put slightly more than $505,000 behind Kepner, setting up a clear money-versus-money contrast as the clock runs down.
Who The Candidates Are
State Senate District 10 covers portions of Alameda and Santa Clara counties and has drawn a crowded Democratic field that includes Kepner, Sakakihara and San Jose councilmember David Cohen, according to KQED. The three present notably different approaches on housing, labor and business regulation, and the wave of outside spending has further sharpened those contrasts.
As the ads stack up, local voters are being pushed to weigh not only policy platforms but also the source of the money paying for the glossy mailers and slick TV spots arriving in their homes and on their phones.
Locals Push Back
Candidates and their local supporters have been trying to push back against the flood of outside dollars. Kepner has said her candidacy is about putting people over profits, drawing a line between her campaign and big-money interests. Cohen told The Mercury News that his campaign is powered by grassroots support rather than large political interests.
Cohen also criticized the level of personal spending in the race, saying that Scott is putting an obscene amount of his own money into the race, according to that reporting.
Why Voters Should Care
Observers say the burst of spending in SD-10 mirrors a broader pattern in California, in which tech and corporate donors are channeling significant money into state contests to shape policy outcomes, as documented in statewide reporting on tech political activity. Analysts also note the relevance of candidates' private-sector ties, pointing out that firms such as Palantir have faced scrutiny over government contracts. Critics argue that kind of work can influence how voters interpret a candidate's record and priorities, according to reporting on the company's activities.
With the primary set for Tuesday, the final round of ads, mailers and independent expenditures could decide which camp, business-backed moderates or labor-aligned progressives, heads into November with momentum.
