So your argument is that Trump could have sabotaged the GOP and decreased the power of The Right, therefore someone like Bernie should sabotage the DNC and decrease the power of The Left? Great idea, genius. That's how we slide further into fascism.
Yes, winning elections and passing progressive legislation is my idea of "working." We've done it before. We should continue instead of pissing our collective pants because it isn't working as fast as you want it to. I see you: you're an accelerationist. You want the pain of revolution because you are too comfortable and entitled, and don't understand what real upheaval feels like. Every accelerationist thinks they will be on the winning side.
