Biden won the white vote in Orange County, CA?!?! (Unless of course ‘white’ includes Hispanic whites.)
I'm guessing Biden narrowly won (Non-Hispanic) Whites there if precinct and city-level swings from 2016 are anything to go by. The county as a whole barely swung D; the more working-class Mexican and Vietnamese areas swung heavily R while everywhere else swung mildly D.
Despite these swings, I still very much struggle to believe that non-Hispanic whites voted fewer than 9 points to the right of the county as a whole.
