US House races in California could shape future of Congress

LOS ANGELES >> U.S. House battles took shape in heavily Democratic California that could tip the balance of power in Congress, while former Trump administration Interior Secretary Ryan Zinke was in a tight match to claim the Republican nomination for a new House seat in Montana.

In Mississippi, two Republican congressmen were forced into runoffs to keep their seats. Rep. Steven Palazzo had been dogged by ethics questions over his campaign spending, while Rep. Michael Guest faced a challenger who criticized his vote on a proposal to create an outside commission to investigate the Jan. 6 Capitol insurrection.

Primary elections across seven states Tuesday set up November contests in dozens of races, as Democrats look to protect the party's fragile majority in the House.

In a diverse district anchored in California's Orange County, Republican U.S. Rep. Michelle Steel, a South Korean immigrant, will face Democrat Jay Chen. The district, which includes the nation's largest Vietnamese American community, is widely considered a toss-up.

In other districts in the nation's most populous state, two Republican House members were trying to surmount challenges tied to former President Donald Trump: One voted to support Trump's impeachment after the U.S. Capitol insurrection, while the other fought against it.

A look at results in key U.S. House races Tuesday:

In 2020, Republican U.S. Rep. Mike Garcia won a narrow victory in a Democratic-leaning district north of Los Angeles. The former Navy fighter pilot was endorsed by Trump that year, then joined House Republicans who rejected electoral votes from Arizona and Pennsylvania and opposed Trump's impeachment after the Capitol insurrection. That record will be a focus for Democrat Christy Smith, who earned a chance for a rematch with Garcia, after losing two years ago.

In a Democratic-tilting district in the state's Central Valley farm belt, Republican Rep. David Valadao is highlighting an independent streak while contending with GOP fallout for his vote to impeach Trump over the Jan. 6 insurrection. Early returns showed him holding an edge over Republican Chris Mathys, who made Valadao's vote a centerpiece in his campaign to oust him. The winner will face Democrat Rudy Salas, a state legislator.

California uses a top-two election format in which only the two leading votegetters advance to the November general election, regardless of party.
