The worst part is they're neither particularly radical, nor very capable of navigating machine politics (like the working families party in New York state), nor do they provide some direction for organizers (like the dsa does, at least locally), nor have they gotten any left wing challengers elected (like justice dems did with the squad). Like all of these institutions have very obvious flaws, but they've done something of note. People's party seems to be mostly posting and they're not even good at that.
