No, I live in Oakland, California. You’d have to drive a couple of hours to find a place that voted Trump in California (like out to farm country and, whooee, aren’t they paying for it now with their lack of farm workers!).
None at all.
I speculate here but…none.
Strangely, in the Bay Area, Trump support (I believe) was only around 10 or 12% of the voters. I suspect those people don’t live in Oakland in many numbers and certainly don’t work in engineering in Silicon Valley a whole lot. Also, they don’t come to my Buddhist meditation group or my tabletop role-playing games groups.
Trump voters are unicorns around here.
Of course, I don’t hang out with cops or in any of the all “whites only” enclaves either.
