My experience has been that even the libs eventually get tired of the high taxes, and move to a low tax state. For many years, New Hampshire was a solid Republican, Conservative State. Then the computer and technology boom started in Massachusetts, which drew all kinds of people, many of them were liberals, to the Route 93/Route 128 belt. After living in Taxachusetts for a while, many of them decided to move to New Hampshire for the country life, and the low taxes, and because Southern New Hampshire was within commuting distance of their jobs in Massachusetts.
But after they got to New Hampshire, many of them decided that they wanted the very same services that they were accustomed to in Taxachusetts. I'd hear them ask questions in town meetings like "Why don't we have street lights?", and "My septic system failed, so why don't we have town sewage?", and "My kid is a good golfer, so why doesn't the high school have a golf team?".
Eventually southern New Hampshire just became another high tax area, with all of the services that they were accustomed to and that caused them to flee Taxachusetts for the country life (now cities), the low taxes (now astronomical), and the commute to their jobs in Massachusetts became a daily gridlock nightmare.
And the rural areas of northern New Hampshire, and which largely had different values than of Southern New Hampshire became run by the huge liberal populations of Southern New Hampshire. And most of those who live in the northern rural areas, are rather upset with the change of political landscape.
This is what I have personally observed over my 62 years, and while living in a rural area that is very close to the US/Canada border, and which has a total population of 23 people, (including children) and who live in a total of 11 households.
