I have to preface this by saying I’m voting for Biden
And this is why things will not change. Why should he, or any DNC member, do anything for you? You have given up the one bit of leverage you have, your vote, and promised it to your designated betters no matter what they do to you and how much they sold you out.
The problem there is, the DNC are the very people helping promote these far right fascists in an attempt to foster that attitude of lesser-evil-ism. There’s been a bunch of leaks on that topic, but still by far the most prominent was 2016 Trump (if you want to know more about that, google “pied piper trump hillary”), and there’s no reason to think they’ve stopped.
I don’t know what the solution is. Voting for any good candidates in local elections, and green in the general (unless one of the other parties does something to earn your vote) maybe? But the problem is so entrenched that I’m not sure it even can be solved by voting. Situation just sucks in general.
