Clearly, the majority of Massachusetts voters have long supported the most depraved (and simultaneously most self-righteous) politicians in the country—going back at least to the Kennedys.
True, but the transplants who came here for college and stayed have had a big effect.
From wikipedia: “Massachusetts is the home of the Kennedy family, and routinely votes for the Democratic Party in federal elections: currently all representatives and both senators are Democrats.
The rural and suburban towns and cities, as well as the South & North Shores, are generally more conservative than the rest of the state, but more liberal than the country as a whole. Places like Cambridge, Brookline, Newton, Somerville, Arlington, Amherst, Northampton, Provincetown, Boston and the islands are considered to be the most liberal cities and towns in Massachusetts.”

All the most liberal places listed are associated with inflow of residents to universities or people who buy pricey coastal properties (Provincetown and the islands). Further, the type of Democrat differs between the working class and the chi-chi set with money to burn (who are often transplants). Of course, that’s true most anyplace.
