UKIAH, Calif. — About 15 people had gathered on the second floor of the Ukiah Brewing Company. The television in the corner was tuned to CNN, and Sen. Bernie Sanders was speaking. This was a pro-Sanders crowd. Nearly everyone stopped what they were doing so they could listen.

Then the band downstairs started playing, and that was the end of that.

I’m here this week learning about The Mendocino Voice, an online news organization started three and a half years ago that is in the process of moving toward a cooperative model of ownership — an innovative step that could help ensure the project’s future. “We are going to be owned by our readers and our staff,” publisher Kate Maxwell told those on hand. “We think that’s the best way to be sustainable and locally owned.”

The Super Tuesday party, which drew a total of 25 to 30 people, was organized by the Voice as a way of bringing the community together to watch not just the presidential results but to find out who had won the primary elections for the Mendocino County Board of Supervisors. There are five supervisors, and three of the seats were contested.

There’s no question, though, that most people were mainly interested in the Democratic presidential primary. Sanders won California easily on a night when the chatter was about former Vice President Joe Biden’s emergence as the clear (though hardly dominant) frontrunner. I was told that Mendocino County, a two-hour drive north of San Francisco, is even more pro-Sanders than the rest of the state. That was certainly true at the Ukiah Brewing Company, where the folks I spoke with expressed their enthusiasm for Bernie over burgers and beer.

“I think the possibility of having a socialist Democrat in the White House is really exciting,” said Rayna Grace, citing Sanders’ “solidarity with the Palestinian people” as well as his support for Medicare for All and for canceling student debt. Her companion, Silver, who declined to tell me her last name, added, “I’m just excited to see a candidate who reflects my radical values.”

Even the only non-Sanders supporter I spoke with said he preferred Sanders to the candidate he actually cast a ballot for — Sen. Elizabeth Warren. “I thought Warren is electable. I don’t know if Bernie is electable,” said John Haschak, a member of the board of supervisors. “Maybe my political calculation is a little off, but we can’t have four more years of Trump.”

Unfortunately for Warren, Haschak’s political calculation turned out to be more than a little off. Warren suffered the worst of what has been a series of bad nights for her, as she came in third in her home state of Massachusetts, behind Biden and Sanders. (WGBH News Senior Political Editor Peter Kadzis breaks down the Bay State results here.) In just a few months, Warren has gone from being the frontrunner to having to do some serious fence-mending with her constituents.

Like many people, I’ve visited California’s urban centers of San Francisco, Los Angeles and San Diego. But this is the first time I’ve been in the rural north. The population of Mendocino County is just under 90,000. Yet, geographically, it’s about two-thirds the size of Connecticut (population 3.5 million) and larger than Delaware (nearly a million).

As is the case in many other places, Mendocino County suffers from a dearth of reliable local journalism. Most of the papers in the county — including The Ukiah Daily Journal, the only daily — were absorbed into the MediaNews Group conglomerate years ago, and have been systemically gutted by the chain’s hedge-fund owner, Alden Global Capital.

Maxwell and Managing Editor Adrian Fernandez Baumann, the Voice’s only full-time staff members, are themselves former MediaNews employees. Though their office — a tiny second-floor room that they rent from a low-power FM radio station — is in the inland city of Ukiah, the county seat, they have positioned the Voice as a county-wide news service. As such, they regularly drive two hours to Fort Bragg, on the Pacific coast, as well as to other parts of the county.

This is weed-and-wine country. The “cannabis economy,” as Baumann calls it, is dominated by so-called back-to-landers, hippies and former hippies who moved to the area in the 1960s. So it’s no surprise that Sanders is the favorite here.

Yes, I did meet a few non-enthusiasts. Before the party, Baumann and I talked with voters outside a polling station at the county offices, where we encountered an older couple who’d cast their ballots for Biden and a volunteer firefighter who’d taken a Republican ballot and voted for President Donald Trump. Overwhelmingly, though, the folks we met had voted for Sanders.

“We’ve been diehard Bernie supporters since the last election,” Moriah McGill told us.

Given Biden’s strong performance across the country Tuesday, it’s no exaggeration to say that voters like McGill, Grace and Silver saved the Sanders campaign. Whether that will be enough to stop Biden is a question for another day.
