I know this is an impossible question, the future is chaos, but we can at least identify and discuss some key factors.
When I say "successful leftist revolution" I mean one that happens soon enough to prevent, or have non-negligible odds of preventing, the collapse of human civilization as we know it due to climate change.
In all likelihood I think we're fucked as far as climate change is concerned, but we should still try to improve our odds. There's no prize for correctly predicting that we're fucked.
Nothing wrong with that. I'd never vote for Biden. I'll probably vote green to try and get them more federal money (that'll probably be taken away anyway but whatever) and there's some important local races that actually make a difference.
the PSL is right fucking there
PSL is polling at nowhere near the 5% threshold nationally and are missing on A LOT of ballots.
The greens are polling less
Not in every state
