well in the USA the democrats like to point out (rightly so) that they are a broad umbrella with a wide range of views and beliefs unlike the republicans who are more notorious for marching in lockstep (conservatism/hate sadly is a pretty strong focalpoint for unity)
however there is a “party platform” published every four years at the convention and it’s a remarkably progressive set of views - if the democrats ever truly accomplished all this, the country would be incredible, the problem it’s a long joke about how the democrats will sooner or later screw themselves over with distraction, corruption or division every time they get some power
