California isn't "very left-wing". It's liberal, centre-left if you're being kind. The democrats are a centre-right party with some mildly-leftist pockets of members.

I am pointing out that HN is not very representative of the US political spectrum, and opinions about what's going on in the US will be filtered based on that. You're largely just hearing from one set of partisans here.

By US standards, California is very left-wing. International standards are not super relevant. (I'm also a bit skeptical of the cliche that the Democrats are a right-wing party internationally. For example, Obama endorsed Trudeau in Canada. But again, not super relevant.)
