Buoyed by a new Congressional map favoring their party, California Democrats were eyeing Tuesday’s primary elections as a critical first step toward flipping a handful of House seats and taking back power in Washington.

Results from California’s massive and slow-moving election process were not immediately clear late Tuesday, as polls closed and mail ballots continued to be processed and counted. Still, Democrats were bullish about their chances of advancing candidates to November’s general election in all five districts that were redrawn in their favor as a result of last year’s Proposition 50 ballot measure.

“The path to winning back the House starts with voting in the June 2nd primary,” the California Democratic Party posted online Monday.

Meanwhile, California Republican Party Chairwoman Corrin Rankin urged Republican voters to make their own voices heard too.

“Like President Trump said, we need to make it too big to rig,” Rankin said on “The Benny Show.” “We need to swamp the vote.”

One of the most closely watched races was in the redrawn 22nd Congressional District in the Central Valley, where incumbent Rep. David Valadao (R-Hanford) is facing challenges from moderate Assemblymember Jasmeet Kaur Bains (D-Delano) and progressive college professor Randy Villegas.

Another closely watched race was in the redrawn 48th Congressional District in San Diego and Riverside counties, where Rep. Darrell Issa (R-Bonsall) decided to retire rather than run for reelection, and where Republican San Diego County Supervisor Jim Desmond — who is endorsed by Trump — is running against a pack of Democrats.

Prop. 50 — which Californians passed with nearly 65% of the vote a year ago — was California Democrats’ response to Texas Republicans redrawing their state’s Congressional maps in the GOP’s favor, at President Trump’s behest. It was also the only major Democratic counterpunch in the wider mid-decade redistricting brawl that has spread across the country in the last year.

Experts expect the redistricting battle to deliver a net gain of a handful or more House seats to Republicans. But Democrats could gain even more ground given Trump’s lousy approval ratings and the long history of midterm election losses for the president’s party.

Combined, those factors make the battle for control of the House incredibly close, which in turn makes the five seats up for grabs in California pivotal — and potentially decisive.

Tuesday’s primaries won’t determine if any of those five seats will indeed flip parties in November. However, the primaries will define those head-to-head races to come and better inform the odds of Democrats toppling Republican incumbents, experts said.

In addition to flipping the seats currently held by Valadao and Issa, Democrats are hoping to pick up three additional seats.

In the 1st Congressional District — which after Prop. 50 lost rural reaches of northeast California and picked up liberal North Bay communities — various candidates were vying for the seat long held by the late Rep. Doug LaMalfa (R-Richvale), who died in January. They include Democratic state Sen. Mike McGuire and Republican Assemblymember James Gallagher, who is endorsed by Trump.

Voters from the existing district are also voting in a special election Tuesday to fill the remainder of LaMalfa’s term.

In the 3rd Congressional District, which lost an eastern rural stretch along Nevada and now holds more tightly to the Sacramento suburbs, Rep. Ami Bera (D-Elk Grove) — who currently represents a different district — is running to remain in Congress in a new seat.

Meanwhile, the 3rd Congressional District’s incumbent, Rep. Kevin Kiley (I-Rocklin), is seeking to do the opposite. He quit the Republican Party, became an independent and is now running for Bera’s current seat in Congressional District 6, which includes the city of Sacramento and Placer County suburbs.

In the 41st Congressional District, which became more liberal after Prop. 50 by losing voters in Riverside County and gaining them in Los Angeles County, a slate of candidates — including Rep. Linda Sánchez (D-Whittier), who currently represents a different district — are running to replace Rep. Ken Calvert (R-Corona). Calvert, a 17-term incumbent, decided to run in the neighboring 40th Congressional District instead.

In the 40th Congressional District, which covers a swath of inland Orange County and portions of San Bernardino and Riverside counties, incumbent Rep. Young Kim (R-Anaheim Hills) is now going head-to-head with Calvert, while also facing several Democratic challengers.

Other districts that were not part of the Prop. 50 shuffle are also attracting attention.

In the 11th Congressional District in San Francisco, several Democratic candidates are vying to replace Rep. Nancy Pelosi (D-San Francisco), the retiring former House Speaker, including state Sen. Scott Wiener; tech millionaire and Democratic political operative Saikat Chakrabarti; and Connie Chan, a member of the San Francisco board of supervisors who Pelosi endorsed.

Democrats are also closely watching several races where younger Democrats and progressives are challenging older incumbent Democrats, and where newer Democratic incumbents are seeking to hold onto their seats in relatively competitive districts.

LOS ANGELES — Outside a Bristol Farms market in LA’s Westchester neighborhood, residents who spoke to Fox News Digital all agreed that homelessness is a top problem facing the city, but disagreed on which mayoral candidate is the right choice to clean it up.

“Love him,” Shelley Zuckerman said about reality television star and independent candidate Spencer Pratt, adding that homelessness is a main motivator of her support for the reality TV star’s mayoral run. 

“The fact that he’s not a politician, so he may or may not be a liar, we don’t know that yet, and I know that he wants to do something for LA that the politicians have been saying they’re going to do and then don’t,” Zuckerman added. “And I know politics works, that once you get in there you can’t always do what you want to do, but at least he’s got the passion.”

SPENCER PRATT SAYS HIS POLICY WILL FORCE HOMELESS OUT OF LA AND INTO CITIES LIKE SEATTLE

When asked if crime was a motivating factor to vote for Pratt, Zuckerman’s husband Saul responded, “Of course.”

The couple says they are supporting Republican Steve Hilton for governor.

Patrick Reynolds, who lives in the neighborhood, said he is “not happy with any of the candidates” and called Pratt a “clown” before saying he voted for incumbent Mayor Karen Bass “a little reluctantly.”

Homelessness has been a top-of-mind concern for voters in Los Angeles, and despite Bass being mayor for the last four years, Reynolds said he believes she’s the best choice on that front.

Reynolds, who said he is supporting billionaire Democrat Tom Steyer for governor, spoke at length about the problems with homelessness, including a local park he said has become “too dangerous” to visit in recent years.

“Homelessness for sure,” a woman named Diane, who said she voted for Bass, told Fox News Digital, “That’s number one on my list, and I think she’s tried very hard to fix that problem. It’s a big problem, I know. And I just think she is down to earth. She’s not some rich billionaire, which I appreciate.”

Diane said she is supporting former Department of Health and Human Services Secretary Xavier Becerra, a Democrat who served in the Biden administration, for governor because he is a “good guy.”

“I like that he is an immigrant and that he has worked his way up in this world,” Diane said. “I think he has a good sensibility. I like also that he isn’t a billionaire. I can relate to him.”

Dan Madden, a resident of nearby Manhattan Beach, told Fox News Digital that if he could vote in LA proper, he’d go with Pratt.

“That’d be my man,” said Madden, who added that he is voting for Hilton for governor. “The last 20 years in Los Angeles has been screwed.”

“It’s getting worse,” Madden said about the homeless situation in the Los Angeles area. “They cleaned up here and there. Spots, especially along the beach, coastline, you see it cleaned up. Two months later, everybody’s back.”

Pratt, a registered Republican running as an independent, faces off in a nonpartisan mayoral primary against incumbent Mayor Karen Bass, a Democrat, and City Councilmember Nithya Raman, a socialist.

Tuesday’s election will determine which two candidates advance to the November general election. If a candidate receives more than 50% of the vote, they will automatically be named the next mayor.

If the last few weeks have shown us anything, it’s that the gubernatorial primary is an unexpectedly close race among a trio unlikely leaders: MAGA Republican Steve Hilton, and Democrats Xavier Becerra and Tom Steyer.

Though Trump endorsed Hilton, a former Fox News host, a Hilton loss may be just what Trump wants — more fuel to fire up his MAGA base with false claims of rigged elections.

“Whether Hilton finishes first, second, or third, Trump will declare with zero evidence that there is voter fraud.,” Matt Barreto told me. He’s a professor of political science at UCLA and a founder of its Voting Rights Project, meant to promote free and fair elections.

And since California will probably take days or weeks to count all the ballots, a tight race will be fertile ground for those fraudulent fraud claims. President Trump has already started, clearly planning to use our primary to further his push to assert federal control of state-run elections.

“You have a really rigged vote in California,” Trump said last week, when asked about Hilton and Los Angeles mayoral candidate Spencer Pratt, another unlikely right-wing contender. “California’s one of the most dishonest states for voting.”

California is not, of course, dishonest in its voting, and Trump has whined about elections for so long that this rhetoric might elicit little more than a shrug from most. But California elections matter at this pivotal moment only months before the midterms. Fraud claims here will further erode trust in our electoral system and could provide Trump with ammunition for interference across the country.

Voter fraud claims may also test a new California law meant to protect real election integrity and trust — a law (Senate Bill 73, signed by Gov. Gavin Newsom last week) that has received little notice but one that could provide a model of protection for the rest of the U.S. It stops law enforcement agents, including federal agents, from “providing unauthorized access, disruption, modification, or seizure of voter rolls, voter lists, or certified voting technology,” without a court order.

Call it the Sheriff Chad Bianco Act.

Bianco, another MAGA gubernatorial hopeful, seized hundreds of thousands of ballots from a recent election, claiming he was investigating the kind of wrongdoing Trump constantly alleges without proof. State Sen. Tom Umberg (D-Santa Ana), a former federal prosecutor, said the warrant Bianco obtained from a friendly judge was “woefully deficient.”

So Umberg helped pass the measure to “protect the integrity of California elections” from “rogue law enforcement officials,” he said.

And he’s not just talking about Bianco.

“I am worried about interference in the election by federal authorities,” Umberg said. “I believe Donald Trump when he says, ‘I’m going to interfere in the election.’”

Umberg is so concerned that he has two other bills in the works he hopes will be law by November. One would stop Immigration and Customs Enforcement agents from being present at polling places. The other would make it illegal for anyone running for a third term as president to appear on the California ballot.

The buildup of fraud claims around California elections and the pushback from legislators like Umberg is a background battle that hasn’t received much attention, but one that is real and consequential.

Trump, through demands for voter rolls by the U.S. Department of Justice, the promotion of the SAVE Act, vague threats of ICE or other federal agents at polls, and the placement of election deniers in key federal rolls has gutted safeguards for voting on the national level.

States have been slow to meet the threat, largely waiting for November to see how it plays out. California, to it’s credit, isn’t so complacent.

The strange circumstances of this particular California election may be a test for both sides. Barreto, the UCLA voting expert, said he thinks “Hilton has the highest probability of finishing first on Tuesday with Becerra close by in second, and Steyer in third.”

But that could — and probably would — change as more ballots are counted.

By Thursday, Barreto said, it’s probable (far from certain) that Becerra is in the lead and Hilton is second.

“There will definitely be millions more ballots counted on Wednesday and Thursday and they will be disproportionately Democratic and contribute to both Becerra and Steyer numbers,” he said.

Maybe pushing Steyer into second? Again, a long shot. But possible.

Democrats have been holding on to their ballots until the last minute this year, with a huge number waiting until just the last few days to vote. It’s possible (though unlikely) that by sheer numbers, Democratic voters will propel both Steyer and Becerra toward November.

We do know that Republicans, despite their smaller numbers, have been voting, and trusting the postal service with their ballots this time around at a fairly high rate. That’s despite Trump’s claims that mail-in voting is inherently fraudulent.

So at the same time that we are expecting a big influx of Democratic ballots in coming days, Republicans may be closer to their voting peak, meaning Hilton’s numbers could top out on election night.

If Hilton doesn’t make the top three, after having been in the lead during in-person voting, MAGA will most certainly lose its collective mind.

And Trump will have something just as good as a Republican governor in the Golden State — “proof” we cheated.
