A look at results in key U.S. House races Tuesday:
Battleground California: Trump history looms in key districts
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. Preliminary 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 vote-getters advance to the November general election, regardless of party.
In the Central Valley, Republican Connie Conway won a special election to complete the term of former Rep. Devin Nunes, who resigned to head Trump’s media company.
