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

If there is something that Americans love to do more than bitching about their elections being rigged, that's not actually participating in said elections and waiting that someone will do voting for them, while they sit around and call everyone who actually votes "libs". That and daydreaming about murdering people during their inevitable revolution/civil war.
That doesn't mean elections aren't actually rigged, they very much are.
