America has pockets of progressiveness so to speak, that's why once in a generation you can get occasional mayoral wins and such. But they never grow into anything bigger, for many many reasons, from the fact that America is a stupid country full of stupid people, to the fact that lefties will always chose infighting and purity checks over pragmatism, to the fact that significant portion left-leaning people are extremely anti-democracy and use "voting" as a slur word.
Doesn't mean nothing can be done, but you also can't just ignore all of that
