Biden actually delivered a lot, and it didn't matter to the left. Once they galvanized around Palestine, his and Harris' intransigent position on that was all that mattered. The only thing Biden could have delivered that would have saved the left was drone strikes on Tel Aviv.

Meanwhile Trump delivers almost nothing of substance and it doesn't seem to matter to the right. They even stopped caring about Epstein as soon as Charlie Kirk's murder gave them something to froth at the mouth about.

I don't know what the future of the left should be but to me it doesn't seem like economic policy is driving either side - even the "price of eggs" thing seems like a post-hoc rationalization for votes people were already going to make. If anything the problem seems to be that the Democrats aren't channeling the outrage of their base as effectively as the Republicans, and there isn't a third option for leftism in the US at that scale. Maybe the left should abandon all hope for the White House and just focus on state-level activism, and build up support for an actual leftist party and agenda.
