I am left of the Democrats, and do not feel represented by what they do (regardless of what they say). I vote in Democratic primaries to try to move the party left. I vote D in the general. But you continue to dismiss what I'm saying. You seem to agree that the Republicans trained their party to move to the right but act like it's some crazy idea that the Democrats are doing the same thing? The wrong side is winning within the Democratic Party, and we're all going to lose everything because of it.
I'm not saying they're a shadowy cabal. They're very openly anti-progressive, no shadows necessary. They spend so much of primary time shitting on progressives and then complain when progressives don't want to vote for their neoliberal hacks in the general.
If you're taking the "progressives are irrelevant" position, please make sure to never blame progressives for the losses of the Democrats. Not even nonvoters. If we're not important enough to justify catering to, then we're not important enough to blame. You don't get to eat our cake and shit in it too.
I quite agree with what you're talking about with local elections.
But you've misinterpreted what I'm mad about. I'm not mad that they don't support progressives. I'm mad that the Democratic Party (the DNC, not your local party chairs) spends more time and effort demonizing and sidelining progressives than learning to work with us. That has effects all the way down to local primary elections where voters who have been fed anti-progressive propaganda are voting against progressive candidates.
What I'm mad about is not the lack of support, I'm mad about the absolutely ridiculous hypocrisy of a party clearly working against progressives at every turn and then blaming us when they don't get their way.
As a side note, I'm also mad that the progressive movement has a lot of real shitty candidates in local elections. Many of them are clearly just absolute weirdos who shouldn't be anywhere near an elected office. But a small movement isn't going to have the reach everywhere. My House rep is progressive, and I get to watch as the person that represents me gets hamstrung by their own party time after time after time. And then the very same Party blames us for Donald Trump. It's absolutely infuriating.
