Joe Biden won California by a landslide margin of 29.2%. Despite Biden's overall victory closely mirroring Clinton's, under a point behind her margin, there were large swings underneath the statewide margins. Biden lost ground in large diverse counties while improving in mostly whiter and more suburban counties. While Trump yet again lost Los Angeles County by a landslide and yet again received less than 30% of the vote in the county, he improved his standing in
Los Angeles County, thanks to growth in mainly Latino neighborhoods in the
Gateway Cities and the
San Fernando Valley, alongside improvements in mainly Asian communities in the
San Gabriel Valley. Trump also managed to gain in white neighborhoods as well, with visible gains made in
Beverly Hills and other
Westside communities, mainly because of the region's high Jewish population,
Burbank and
Glendale in the eastern San Fernando Valley, and the Valley's southern wealthy neighborhoods such as
Encino and
Tarzana. California is also one of the seven states (along with
Illinois,
Arkansas,
Nevada,
Utah,
Florida, and
Hawaii) as well as the District of Columbia in which Trump's margin increased from 2016. While Biden won
Santa Clara County by a landslide margin of 47.4%, his margins shrank below that of Hillary Clinton's 2016 margin, 52.1%, in the county. His margins slightly shrank in the more suburban communities of
Santa Clara and
Sunnyvale, even improving in very wealthy cities like
Los Altos Hills and
Saratoga, but his margins fell in the heavily Asian parts of
San Jose, and
Milpitas, which Biden won by a landslide, as Trump's comparison of Biden's proposed policies to socialism and communism drove
Vietnamese American voters towards him. The
issue over China in the South China Sea helped swing Vietnamese Americans, as well as
Filipino American voters to the Republican Party. Nonetheless, Trump still received a small 25% of the vote in Santa Clara County, underperforming President Bush in 2004, John McCain in 2008 and Mitt Romney in 2012. Trump also gained in
Alameda and
San Francisco County, but his improvements were smaller than
Santa Clara County and
Los Angeles County. In the former, Biden's improvements in wealthy suburban areas, like
Carlsbad and
Encinitas, alongside gains in more working-class
Escondido and
Oceanside, helped overcome Trump's growth in the more Hispanic neighborhoods in southern San Diego County. In
Riverside County, Trump lost ground in whiter more Republican territory in the southern part of the county like
Menifee and
Temecula, and in very liberal communities like
Palm Springs in the
Coachella Valley, which overcame Biden's decline in Hispanic communities towards the county's northwest, including
Moreno Valley and
Perris. Biden improved by a point in
Sacramento County but saw visible growth in suburban
Placer County. However, Trump overwhelmingly outperformed his 2016 performance in rural and heavily Hispanic
Imperial County, gaining 17 points. Biden's margin was higher than John Kerry's or Al Gore's in Imperial County, but underperformed Barack Obama and Hillary Clinton.
