If you look at just the Anglo population, after Vermont (and DC but I'm not counting that), would not Massachusetts be in the hunt for the number two slot as to its liberalness/progressiveness? Sure a few other states would be competitors (Hawaii and WA come to mind), but MA might have an edge.
Forgetting about the white working class, and just focusing on your class, eh?
I think the west coast is more liberal than MA, but I'm talking about social liberalism. Socal is about the same though. The bay area, Portland, Seattle and a bunch of areas of the coastal west are more liberal.
I guess I was focusing more on voting patterns. And sure some portions of some states are more liberal among Anglos obviously. But statewide overall?
