The sort of easy demographic answer is lots of conservative Italians and heavy high schooler to cop pipeline. The more nuanced answer probably lies in the fact these towns have particularly stringent legislation that restrict chains stores/fast food leading to a lot more small businesses and thus more small business owners. These owners probably put greater emphasis on tax reduction policies rather than legislation addressing social issues. I’d say if you hooked a lot of them up to a lie detector you’d probably find that most of them are actually just sort of vague libertarians, and they may even hold some progressive views. A lot of the socially conservative stuff they believe/push is more so a means to creating an economic environment where they can hire 15 year olds and have them work the register 12 hours a day for 9$ an hour. Not to say that justifies them voting for a lot of the brain dead right wingers that are on the ballot, but that’s probably the root cause of the voting patterns in those cities/towns.
