Villaraigosa has never run for a statewide office before. So he has also been campaigning and raising money in California's agricultural Central Valley, not usually fertile soil for Democrats.

Some polls have shown him in second place, some in third, one in fourth. He hasn't held public office for five years. But his name recognition is likely to rise, courtesy of millions of dollars in independent expenditures from wealthy advocates of charter schools.

Sharing second, third and fourth place in the polls with Villaraigosa are two Republican candidates. John Cox is a businessman from Chicago who has never held elective office, though he has run for several of them. His Republican rival is state Assemblyman Travis Allen of Huntington Beach, who touts his Southern California roots and his love of surfing.

At the state GOP convention in San Diego last weekend, Caroline Abate stood outside the hall waving signs for both Cox and Allen. "Endorse somebody!" she pleaded with delegates.

Republicans need to choose one of these guys, Abate said, and she didn't seem to care which one. A party endorsement will unify Republican voters, she said, because "if they split the vote, Antonio Villaraigosa is going to get No. 2 ... and it's going be over for Republicans in June."

On paper, Cox and Allen seem to check the same boxes. They both support President Trump's plan for a border wall. They both want to repeal the recent California law that protects undocumented immigrants. They both want to dump an increase in the tax on gasoline.

Their big differences are in style.

John Cox looks every bit the distinguished, older business executive, and he sees the state through that lens. He told convention delegates that California has been mismanaged and that it'll take a businessman to fix it.

"Business people solve problems," Cox said. "[They're] not a bunch of rhetoric, not a bunch hot air. They get results and that's what people want."

While Cox is using part of his personal fortune to fund his campaign, his opponent's campaign is running on fumes. Allen tries to make up for it with boundless confidence and by touting his early and passionate support for Donald Trump, whom Cox did not vote for.

"Did we take back our country in 2016?" Allen asked to the cheers of the crowd. "Are you ready to take back our state in 2018?"

In the end, neither Allen nor Cox could muster enough support to win the party's endorsement. It looks like they'll be fighting for the same dwindling pool of conservative voters until primary day, decreasing their chances of making the runoff. Delegate Karen Roseberry found that prospect alarming and begged the delegates to reconsider. There is so much more at stake, she said, than just the governor's race.

"Every down-ticket race is counting on this," she said. "We need a top-2 finisher in November, and that comes when the party is united."

Those down-ticket races worrying Roseberry include at least half a dozen vulnerable Republican House seats. If Democrats can grab those, it would help them tip the balance of power in Congress. No one knows what the impact on Republican turnout will be if there are only Democrats to choose from in the California governor's race. But Republicans are hoping they won't have a chance to find out.
