"Right now, the California Republican Party is as dead as you can imagine. … It’s ashes.”

After decades of decline and a devastating 2018 election cycle that gutted an already decimated state party, the GOP’s more moderate wing is gearing up for a state convention this weekend that some argue is its last opportunity to avert collapse.

A battle over the state party chairmanship offers two competing visions for the future. One embraces President Donald Trump; the other focuses on the nuts and bolts of party building and organizing.

The two approaches aren’t complementary. Trump, who lost California by 30 percentage points in 2016, is highly unpopular there: Nearly two-thirds of California's voters disapprove of his performance as president.

“What it really comes down to is whether a party’s first obligation is to motivate its base — or to reach out beyond that base,’’ said Dan Schnur, a former GOP strategist and adviser to Sen. John McCain who is a professor at the University of Southern California’s Annenberg School for Communication and Journalism and is now an independent. “We’ll see what they decide.”

As it stands, the Republican Party in the nation’s most populous state is barely breathing. The midterm elections saw the landslide victory of Democratic Gov. Gavin Newsom, Democrats win supermajorities in both state legislative chambers and the flipping of seven GOP House seats.

Whomever California Republicans elect to succeed Jim Brulte, the former state senator who has led the party for six years, won’t be able to reverse the party’s fortunes anytime soon. But he or she might be able to halt the downward spiral. For weeks, candidates have been lobbying, mailing, phoning and campaigning up and down the state to offer their prescriptions.

Jessica Patterson, the CEO of the California Trailblazers — a candidate-recruitment program blessed by House Minority Leader Kevin McCarthy — has racked up the lion’s share of endorsements from the state's GOP elected officials.

A Latina from a Southern California working-class family, Patterson voted for Trump. But she argues that her leadership of Trailblazers has armed her with the experience and the strategic knowledge necessary to build the state party back to its former strength — and reassure key donors regarding its rebound.

In her view, Republicans must “stay on message” — jobs, economy, education, pro-business policies — and concentrate on the damage the ruling party has done in Sacramento.

“Some people have already given up on my party, and they say it’s not salvageable,’’ Patterson told POLITICO. “I don’t accept that. I love my party too much.’’

But the two conservative grassroots activists who are challenging her lay the blame for the 2018 battering at her feet.

Former gubernatorial candidate Travis Allen, a former state assemblyman and a fire-breathing favorite of tea party activists, derides Patterson as part of a status quo that has "produced a record of abysmal failure in GOP politics in California."

"The GOP establishment has told Republicans for years that they need to look and sound more like Democrats — to be Republican-lite," he said.

Allen argued that the GOP establishment has not shown the robust support for Trump that the president deserves — and that he contends would fire up and energize the GOP base.

“Clearly, the Republican Party must stand for Republican values — and the Republican president,’’ he said. “This is truly a Republican president who has delivered — and among the 4.5 million Republicans in California, I have yet to find a room that is not overwhelmingly in support of him.’’

Allen, who backs Trump's anti-illegal immigration rhetoric and his call for a border wall, is reprising the populist rhetoric that marked his failed campaign for the 2018 GOP gubernatorial nomination — and helped him amass an unprecedented mailing list of 25,000 activist GOP donors and supporters.

The nominee, the more moderate multimillionaire businessman John Cox, admitted he didn’t vote for Trump and lost in a landslide to Newsom.

“I’m the candidate who has the energy to take back the entire state,’’ he said. “We need excitement in today’s California Republican Party ... a bold new vision that is built by Republicans, for Republicans — and who believe in Republican values.”

But Allen may end up splitting the conservative grassroots vote with another anti-establishment Republican, Stephen Frank, the publisher of the conservative newsletter California Political Review.

A former party official whose roots in state GOP activism go back decades, Frank lambastes the current state party leadership, saying it “has unilaterally disarmed,’’ failed to mount competitive candidates and voter registration campaigns, and was outplayed by the Democratic Party in the 2018 elections, in which Democrats flipped House seats with aggressive practices like ballot harvesting.

Worse, he said, the state GOP lacked a cohesive message on key issues like education and job opportunities — even while it ran away from President Trump.

“We were being told Trump is so poorly liked in this state that we shouldn’t talk about him,’’ said Frank, who’s a regular on conservative radio stations. “We should have been talking about the miracle of the economic recovery under Trump, his willingness to stand up in trade negotiations, his ability to stop ISIS, and his creation of 400,000 manufacturing jobs. …We were so afraid of saying 'Donald Trump' that they forgot the great stuff that Trump did."

Those divisions mirror the battles waged within the national Republican Party, he said, in which Trump’s base defends the president’s positions and sees his leadership as the key to future electoral successes even as some mainstream Republicans in elected office wince at his rhetoric and effects on the GOP brand.

GOP consultant Robert Molnar, advising Frank, said 2018's results put the problem in stark relief. "We have lost seats every cycle. ... How are you touting that a success?’’ he said. “It’s been a total failure. They’re not even an opposition party at this point. Right now, the California Republican Party is as dead as you can imagine. … It’s ashes.”

Leading Republicans say the situation will deteriorate even more if either Allen or Frank claims the chairmanship. Former Assembly Minority leader Chad Mayes pushed back against Allen's jabs at the GOP establishment and elected officials. He tweeted a prediction that if Allen wins the chairmanship, “more sitting legislators will leave” the California Republican Party.

“Winning in politics requires addition,” Mayes said. “Demagoguery and division proves to be a losing strategy.”
