Who are Kamala Harris and Donald Trump’s top donors in Sonoma, Napa and Marin counties?

North Bay residents have dug deep into their pockets this election cycle, with some pouring hundreds of thousands of dollars into a presidential race widely considered one of the most consequential in the nation’s history.

But if there’s any doubt about who the region’s big donors are favoring, recent campaign finance reports leave no doubt: Vice President Kamala Harris’ campaign received $10.5 million from individual donors in the six counties north of San Francisco, while former President Donald Trump’s campaign received nearly $1.3 million.

Counting contributions to the political action committees supporting both candidates, donors in Sonoma, Napa, Marin, Mendocino, Lake and Solano counties have distributed a total of $18.4 million in the 2023-2024 election cycle. The bulk of those came from Sonoma County, where those donations totaled $8.4 million, and from Marin County, where they totaled $7.5 million, Federal Election Commission data show.

Determining comprehensive amounts and rankings for individual donors in the presidential race and other federal campaigns can be difficult. One reason is that people can also give money to organizations called “joint fundraising committees,” which in turn can transfer portions of that money directly to candidates’ campaigns, while the rest is spent on other political activities on behalf of a candidate .

Some of the largest North Bay contributions that benefited Harris and Trump went to these joint fundraising committees, with individual contributions running into the hundreds of thousands of dollars. Because it is difficult to avoid some degree of it double counting, The Press Democrat, with help from the nonprofit, nonpartisan campaign finance watchdog OpenSecretsdid a separate accounting of the Joint Fundraising Committee, or JFC, donations to both candidates. In total, the JFC tab was almost $17.7 million.

Joint fundraising committees tied to Harris received nearly $15.5 million from the North Bay, while Trump’s joint fundraising committees received nearly $2.2 million from donors in the region.

The largest amount donated by an individual or an organization in the six-county area came from Federated Indians of Graton Rancheria, who contributed $4 million to a super PAC called Californians for Choice, whose stated goal is to rally pro-choice voters to defeat Trump and win key congressional districts in California.

During the current election cycle, the Sonoma County tribe, which runs the Bay Area’s largest casino-resort, also made four donations totaling more than $1 million to the Biden Victory Fund’s joint fundraising committee, which later became the Harris Victory Fund.

In one example of the money transfer between JFCs and campaigns, $6,600 was sent directly to Harris’ campaign. Direct contributions to candidate campaigns are limited to $6,600 per election cycle.

Other names populating the list of top North Bay donors for Harris include prominent millionaires and several billionaires, including Daniel Pritzker, one of the heirs of the Chicago-based Pritzker family. Pritzker donated $900,000 to the Harris Victory Fund, making him the lead individual donor to a joint Harris fundraising committee. It also features Colleen, Elise and Robert Haas from the family behind San Francisco-based Levi-Strauss & Co. ($410,025).

Other notable figures include a prominent Bay Area attorney and a Sebastopol resident Elizabeth Cabraser ($459,200); Harrison MillerMill Valley resident and senior advisor for Summit Partners, a global growth equity investment firm ($272,990); and Dee and Richard Lawrence, Greenbrae residents and co-founders of Cool effect, a Bay Area nonprofit focused on reducing global carbon emissions ($563,200).

Top donors to Trump’s campaign, joint fundraising committees and associated PACs include Napa County vintner W. Clarke Swansonfounder of Swanson Vineyards and heir to the Swanson family of frozen food fame ($53,409); And David GrieveA Winery owner in Napa Valleyreal estate investor and founder of a restaurant investment group behind 300 Taco Bell and 28 Arby’s franchise locations nationwide. Grieve’s $100,000 to the Trump 47 Committee ranked him as the top Trump JFC donor from the North Bay.
