On Massachusetts yeah the West Side of the state of the state is liberal like Amherst. Of course Boston is pretty liberal too. Worcester isn't really that liberal though. I think Republicans like Scott Brown and the 2010 Republican Nominee for Governor Charlie Baker did well in the Eastern Part of the state. I mean a few districts in the Eastern Part of the state were trending Republican before the Redistricting happened(MA-3, MA-4, MA-6, and MA-9.)
It's really just some of the Boston exurbs and parts of Worcester and Plymouth Counties that are Republican as such in Massachusetts, and even then a lot of the more conservative people who would otherwise live there fled to southern New Hampshire in decades past. Places like the suburbs of Springfield, Essex County outside its cities, Norfolk County less Brookline and Quincy, and Cape Cod are a bit squishier politically and give Republicans a lot of such statewide victories as they get.
