Eight Democrats and two Republicans have filed officially to run for California governor by the Friday deadline. The crowded field could give GOP candidates a boost.

It’s official: Eight Democrats and two Republicans say they have filed paperwork for the June 2 primary ballot in the California governor’s race, setting up a wide-open contest in which two Republicans who have consistently led in polls could shut out all other Democrats.

Here are the 10 candidates:

  • Xavier Becerra, Democrat, former U.S. Health and Human Services secretary and former California Attorney General
  • Chad Bianco, Republican, Riverside County Sheriff
  • Steve Hilton, Republican, Fox News contributor and former adviser to conservative British prime minister David Cameron
  • Matt Mahan, Democrat, mayor of San Jose
  • Katie Porter, Democrat, former U.S. representative representing Orange County
  • Tom Steyer, Democrat, billionaire entrepreneur and former presidential candidate
  • Eric Swalwell, Democrat, U.S. representative from the Bay Area
  • Tony Thurmond, Democrat, state superintendent of public instruction
  • Antonio Villaraigosa, Democrat, former mayor of Los Angeles and former Assembly Speaker
  • Betty Yee, Democrat, former state Controller

Steyer became the last to officially file on Friday, the deadline for submitting candidacy paperwork.

Former Assembly Majority Leader Ian Calderon exited the race earlier this week, endorsing Swalwell instead.

What’s next?

The secretary of state’s office says it will verify the paperwork their campaigns submitted and publish an official list of primary candidates by March 21.

The top two vote recipients in the primary, regardless of party, will advance to the general election. But the two Republican frontrunners enjoy more consolidated support from their base than their Democratic counterparts, who risk fragmenting the Democratic vote. At the February state Democratic Party convention, delegates were so split that no candidate earned enough votes for the party endorsement.

With the current field, there’s a 27% chance of a Republican faceoff in November, according to statistical modeling by Democratic strategist Paul Mitchell.

The prospect is worrisome for many Democratic leaders, including state party leader Rusty Hicks, who earlier this week penned an open letter calling for those without a “viable path” to victory to drop out before the Friday deadline to file paperwork. And for those who remained, he pleaded, drop out by April 15 at the very latest if they couldn’t make “meaningful progress.”

The call appeared to fall on deaf ears, as eight of the nine announced Democratic candidates stayed in. Even if someone drops out now, their name will still appear on the primary ballot as long as they qualify, risking siphoning votes away from other Democrats.

Discounting the risk

When asked about the risk of a November shutout at a Thursday gubernatorial forum, several Democratic candidates brushed it aside while insisting they each would be voters’ best choice.

Villaraigosa told CalMatters the GOP base will coalesce behind just one candidate when President Donald Trump makes an endorsement.

“When that happens, that person is going to surge up and the other (Republican is) going to go down, it’s as simple as that,” he said.

Of the Democratic attendees at the forum, only Porter acknowledged the risk of a crowded field of Democrats.

“I think it is terrifying to think about what Trump would do to Californians if we had a governor who at every turn cooperated with him rather than stood up for our California values,” she said. “So I don’t think it’s a certainty, but I do think it’s a risk, and I think the stakes are very, very, very high.”
