Vermont shifted from most Republican to most liberal state
Vermont shifted from most Republican to most Democratic, but it's always been relatively "liberal". Vermont switched parties not long after the parties themselves swapped relative positions. There was an influx into Vermont of outsiders (mostly from Massachusetts), but that isn't nearly enough to account for its change in partisan affiliations. The Berkshires in MA have for a long time been pretty poor and economically leftist, and western MA hasn't seen nearly the same type of immigration as Vermont.
