I'm surprised Trump didn't win Worcester and Hampden counties in MA- Worcester is somewhat similar demographically to Plymouth (both are 85% white and voted slightly over 40% Trump), and Hampden is around 70% white and virtually all the Democratic voters there live in the majority-minority areas like Springfield and Holyoke.
Clinton won every precinct in Holyoke and Springfield including the predominantly white ones. Even though they're minority-heavy cities, the whites there and in Chicopee and Longmeadow can probably outvote people in places like Southwick and Monson. Same goes for Worcester and its surroundings.
