You make a good point. If only you knew how hopeless I feel with what we're offered.
There's something you could have been doing all along but it's not too late to start:
Stop supporting (voting or apologizing for) democrats and republicans.
They've only been allowed to pull their scam and offer such increasingly unpalatable candidacies because people refuse to cut their losses and tell them both to go fuck themselves.
Even candidates who make "progressive" noises like AOC and 'the squad' are, well-intentioned or not, immediately folded into the establishment and rendered as performative as Pelosi or Feinstein or any other old guard you care to name.
Don't listen to what they say... watch what they do.
As long as democrats and republicans are still being elected they have no incentive to change at all.
