Fremont Democrat Ro Khanna has defeated eight-term Rep. Mike Honda (D-San Jose) in their bitter, intra-party matchup in Silicon Valley.
Honda, a longtime progressive voice in the Bay Area, was believed to be one of California's most vulnerable congressional incumbents after he received fewer votes than his challenger in June's primary.
Khanna, who also challenged Honda in 2014, argued that Silicon Valley voters needed a change in leadership.
If passed, Measure LV would require voter approval for most development projects taller than 32 to 36 feet. That threshold would cover many new apartment and condo developments, as well as office and retail projects.
Without the growth limits Measure LV would impose, backers say more developers will tear down existing housing and build even more luxury developments that could price out Santa Monica's renters.
Bay Area measures that seek to restore BART and extend the commuter rail system to downtown San Jose were ahead Tuesday in early returns, both of which require a two-thirds vote to pass.
In Santa Clara County, Measure B asked voters to raise the sales tax by half a cent for every dollar spent to fund a host of freeway and transit improvements, including funding to bring BART to downtown San Jose, raising more than $6 billion over the next three decades. Measure B was garnering 71% support with an estimated 44% of the ballots counted.
Voters in San Francisco, Alameda and Contra Costa counties were deciding the fate of Measure RR, a $3.5-billion bond measure to rebuild the core systems of the aging electric train service, which has been plagued with ancient, faulty power systems and water leaks that have weakened steel rails so much they crack during the commute. With 76% of the precincts reporting, Measure RR was garnering 70% of the vote.
Lou Correa will be Orange County's newest congressman, the AP projects. Correa prevailed in his fight against fellow Democrat, Garden Grove Mayor Bao Nguyen, in his race to replace Rep. Loretta Sanchez (D-Orange) in the 46th Congressional District.
As of midnight Wednesday, Correa was leading by a wide 70-30 margin, with 48% of precincts reporting.
Correa, a veteran politician who has represented the area in the state Senate and Assembly, lost narrowly in a 2014 bid for a seat on the Orange County Board of Supervisors.
Hillary Clinton has conceded defeat to Donald J. Trump, ending her quest to make history as the nation's first female president.
Clinton did not speak publicly, as Tuesday night turned to early Wednesday morning on the East Coast. But as Trump addressed his supporters, the president-elect announced he had spoken with his former rival.
"She congratulated us," Trump said, "and I congratulated her and her family on a very, very hard-fought campaign."
