I'm talking big picture. The working class has been clearly pissed about the economy for a long time and the DNC left that void for Trump to fill because they don't actually want progressive economic change. So I see all of this as the inevitable repercussions of the DNC's major fuck up in 2016 (and 2020) - when they made it very clear they would do everything they could to prevent a true progressive from winning.

As for this last election in particular: they could have tried to pressure Biden to drop out much earlier, actually hold a proper primary, and lean into their base instead of trying to court the middle-right like they always do.
