The left loses anytime the DNC stops a working class candidate in their openly rigged primaries.

He got screwed by the super-delegate system in 2016 (which i would conflate to rigging but it was the known caucus system at the time.) in 2020 when they got rid of that system and moved to the primary system he lost on that super tuesday when all the candidates bowed out and transferred their delegates to biden, again i can understand calling that rigged but it's within the rules of the primary.  Biden also just won more votes, we can definitely chalk it up to media coverage of biden vs bernie. Keep in mind that the party elections are not federal elections bound by the rules of the constitution. "Openly rigging" sounds more like changing votes which isn't what happened, the rules are made to get the "safest" candidate in.

I think a major issue is trying to start a progressive party inside the democratic party instead of grass roots local movements. Realistically we're not going to jump from dem/republican federal leadership to a progressive. especially from within one of those parties.

Ironically if they kept the superdelegate system, biden would not be the presumptive nominee because the super delegates wouldn't be bound to him and could change their support regardless of bidens refusal to release his. Not saying its a great system but its pretty funny.
