It’s not a new idea, we just haven’t been implementing it. And who said anything about pushing the liberal party left? It’s not about parties, it’s about politicians and their policies. Run third party wherever it’s viable, run Democrat where it isn’t, it’s really not that important what letter is next to your name. What’s important is your platform.

definitely isn’t a distraction from organizing the working class into a force of its own

That’s exactly what I’m suggesting. What is “showing up to every election to vote for progressives” if not organizing the working class? What kind of organization do you think has a lower barrier than voting? If we can’t organize the working class to vote one day every couple years, how on Earth do you expect them to jeopardize their safety and livelihoods with more direct action?

And even then, those approaches aren’t mutually exclusive. Voting in no way prevents you from organizing. In fact, strategically voting against the fascists explicitly helps the push to organize. It’s much easier to protest when the reaction is a smug “I’m talking now”, than when the reaction is having your degree retroactively nullified or, y’know, getting deported to an El Salvadorian gulag.
