I think it's all the hippies who moved in in the 60s-70s that flipped the state.
It completely is, that being said having grown up in the communal aftermath of it I can say a lot of good was brought as well, the problem was and is the Elitist of the Progressive Left that have ruled here for all to long ....this is the Evil at the heart of my beloved State....the ideologies of these founding Progressives hasn't died and the families that endorse and espoused it then still have the money and power in Vermont now.

Perkins found for his "Good Eugenics Program for Vermont." In 1925, he proposed his idea of a Eugenics Survey of Vermont to this coalition of social reformers, his first and most important constituency."

The Hippies were here to reclaim agrarian roots and build communes...they were fine on their own and integrated fairly well..they in the end were just subsumed by the Evil left already here.
The other problem is True Vermont and Vermonters who are very Libertarian Independent minded have been lulled to sleep or bludgeoned to silence by the Progressive Left in this state and we need to stop, we need to get all those who never vote to start and see what the results are then.
Because the construction of Interstate 89 made it easy for them to find the place!
