Your analysis is based on a glance at a site lmao.

UP is the electoral arm of another larger, radical organization. The point of it is to act as a tool for taking radical rhetoric into the elections and recruiting for the other, more openly ML and revolution-focused groups. It is not a whole thing in itself, just a tool of another larger movement.

It is still a relatively new organization, though. They are ever more consistently showing up amongst organizers of events and lower level institutions, like universities.
