Republicans and Democrats awaited the outcome of vote-counting for crucial U.S. House districts in California on Wednesday, as the GOP clinched majority control of the chamber next year with a race call in neighboring Arizona.

In a rematch from 2022, Rep. Ken Calvert — the longest-serving Republican in the state’s congressional delegation — defeated rival Democrat Will Rollins in the 41st District, which lies east of Los Angeles and was a top target for national Democrats.

In Southern California’s Orange County, Democrat Dave Min defeated Republican Scott Baugh in a closely divided swing district, ending Baugh’s bid to seize the seat being vacated by Democratic Rep. Katie Porter in what was once a conservative stronghold.

The 47th District, southeast of Los Angeles, was a top target for national Republicans looking to protect and possibly expand the their narrow majority.

Calvert, who was backed by President-elect Donald Trump, claimed his 17th term in a district narrowly carried by Trump in 2020.

“This is a hard-fought victory that shows voters want someone who will put results above partisan politics,” Calvert said in a post on the social platform X.

Min, also posting on X, said that in Congress he will “fight to protect our democracy, safeguard our freedoms and expand economic opportunity.”

Baugh said on the same platform that “despite running a strong campaign … that effort is going to come up a little short.”

On Tuesday, Republican Rep. David Valadao’s victory in California’s 22nd District moved Republicans within two wins of retaining the House gavel, with the tally 216-207 in favor of the GOP, as counting continued in a sliver of races across the country.

With Calvert’s win, the Republican tally reached 217. That became 218 on Wednesday night, securing a majority margin, as Rep. Juan Ciscomani won reelection to a seat representing southeastern Arizona. Some squeaker races remained in play in California.

In the 45th District, anchored in Orange County, Republican Rep. Michelle Steel’s lead over Democrat Derek Tran was whittled down to a few hundred votes as counting continued.

California is known as a liberal protectorate — Democrats hold every statewide office, dominate the Legislature and congressional delegation and outnumber registered Republicans by a staggering 2-1 ratio. Still, Republicans retain pockets of political clout in the Southern California suburbs and vast rural stretches, including the Central Valley farm belt.

Orange County was once considered conservative holy ground, where white, suburban homeowners delivered winning margins for Republicans year after year. It was a foundational block in the Reagan revolution. But the county has become more demographically diverse and Democratic over time, like much of the state.

The 47th District, which includes Huntington Beach and other famous surf breaks, has been occupied by Porter, a progressive favorite who in 2022 narrowly defeated Baugh, a former Republican legislator. Porter, known for grilling CEOs during Capitol Hill hearings, stepped aside to run for U.S. Senate, but lost in the primary.

Given the stakes in the closely divided district, the contest was especially rancorous. Min ads called Baugh a “MAGA extremist” who would endanger abortion rights. Baugh said Min’s “extreme liberal views” were out of step with the district.
