I feel like the dems in the US (and many like them elsewhere in current times) struggle with purity politics whereby they either ditch those who could provide them vital support in their quest for purity on some fronts and espouse a pure stance on other fronts but drastically undermine that image.

It's hard to be the party that is aligned with opposing large capital in the public consciousness whilst at the same time bending over and pushing these purists out of the way for donations from said wealth. A party with a subset of oppose police or wants to see it's role redefined with a kamala as a frontrunner. A party that on occasion tries to make itself seen as having the stance and solution regarding things like housing but then not adequately doing so where they have an uncontested stronghold.
