California Democrats dominated in pivotal congressional races in Tuesday’s election, soundly defeating or holding commanding leads over Republican candidates from the state’s northern redwood forests to the Mexican border.
The election marked the first test of California’s new congressional district lines approved under Proposition 50 in 2025, a counterpunch to President Trump’s push to get Republican-led states to redraw their electoral maps to keep Democrats from gaining control of the U.S. House of Representatives — a GOP effort that flopped in spectacular fashion Tuesday.
“We fought fire with fire,” Gov. Gavin Newsom said on X on Wednesday. “And won.”
In the Central Valley, voters swept out Republican David Valadao, a longtime incumbent and dairy farmer in the San Joaquin Valley who batted away Democratic challengers for years. Valadao lost to Democrat Randy Villegas, a professor and school board member who was endorsed by Sen. Bernie Sanders (I-Vt.) and is aligned with the Working Families Party.
In Northern California, Republican-turned-independent Rep. Kevin Kiley lost to former state Sen. Richard Pan, a Democrat, for a newly suburban and rural seat in and around Sacramento. And in Southern California, Democrat Marni von Wilpert beat out a Republican candidate for a new district stretching across San Diego and Riverside counties. Parts of the district previously had been represented by Republican Rep. Darrell Issa, a longtime politician who opted not to seek reelection.
Tuesday’s wins in California were part of a national trend, with Democrats seizing control of the U.S. House of Representatives, the Senate and several governor seats.
As victors were declared on Wednesday morning, some political analysts downplayed Proposition 50’s effect. Instead, they credited Democrats’ success in California to voter discontent after two years of rising tariffs and gas prices, and immigration raids in the Golden State.
Democrats would have triumphed regardless, said Republican consultant Rob Stutzman, pointing to widespread anger over Republican policies, including that party’s push to retain control of the U.S. House through a highly unusual mid-decade redistricting experiment in some states.
“These are all things that activate Democrat voters, and things that alienate middle of the road voters. It’s just too much arrogance, too much power grab,” Stutzman said.
Newsom and other Democratic leaders campaigned for Proposition 50 in hopes of unseating five Republican incumbents in the state’s 52-member congressional delegation, the largest in the nation. The measure asked voters to approve new congressional district lines designed to favor Democrats for the 2026, 2028 and 2030 elections, overriding the map drawn by the state’s nonpartisan, independent redistricting commission.
Republicans’ redistricting efforts failed to reap them wins in several states, including in Texas.
Paul Mitchell, a Democratic redistricting expert who devised California’s new congressional map, disputed the notion that Democrats would have picked up five California congressional districts without Proposition 50 and argued Tuesday’s election showed the state was the most successful amid the nationwide redistricting wars.
“It would have been foolish for Democrats to sit back on their butts and say the future is going to take care of it,” he said, adding that Proposition 50 “crystallized” Democrats’ fight and “brought voters along.”
In another highly watched race, Rep. Adam Gray, a Democrat from Merced, won reelection after easily cruising past Republican challenger Kevin Lincoln. The perennially competitive district — which stretches from Madera through Merced and includes portions of Stockton — became more favorable to Democrats after it was redrawn under Proposition 50 to add urban voters.
And in Northern California, state Sen. Mike McGuire (D-Healdsburg) beat out Republican Rep. James Gallagher of Yuba City, who won the seat in a special election earlier this year after the death of Rep. Doug LaMalfa. The newly configured district includes Santa Rosa, Paradise and Susanville.
In Southern California, a match-up between two longtime Republican incumbents saw Rep. Ken Calvert of Corona beat Rep. Young Kim of Anaheim.
Calvert retained about half of the voters from his former district heading into Tuesday’s election, while Kim retained about a third. The new maps under Proposition 50 created a district that consolidated conservative voters in Orange and Riverside counties.
In Los Angeles, Angela Gonzales-Torres, a democratic socialist, beat Rep. Jimmy Gomez for a district stretching from Koreatown to East L.A. and the northeast communities of Eagle Rock, Highland Park and El Sereno.
Gonzales-Torres’ victory marks a success for progressive groups, which have long targeted Gomez’s seat. The U.S. House Ethics Committee this summer announced an inquiry into Gomez, elected in 2017, over alleged “inappropriate sexual contact with a House staffer.” He has denied wrongdoing, while acknowledging mistakes outside his marriage.
Other Democratic-against-Democratic races were too close to call, including a race for a district in Napa and Sacramento valleys between incumbent Rep. Mike Thompson (D-St. Helena) and his challenger from the left, venture capitalist Eric Jones.
