That's in part because Haris's campaign sucked shit (she spent more time on the trail with Liz Cheney than her own VP), in part because Biden's "booming" economy couldn't seemed to rectify the same escalating wealth imbalance we've been drowning in since Ford/Carter, in part because generations of voter disenfranchisement have stacked the deck against liberals, and in part because 15M D voters didn't show up between 2020 and 2024.

But the idea that "casual" voters of any strip don't exist really ignores how many Obama-Trump-Biden-Trump voters just flit in the wind based on however they're feeling at a given moment.

What's more, if the US has an underlying ideology, it tends toward fascism. Liberals don't want to grapple with that, so they end up offering up half-a-fascism to the moderate voter and telling the Radical Antifa Leftists to pound sand every four years.
