I think growing up in Tax-a-chusetts in the 60s and 70s, watching the Kennedy's monarchy reign over that place is one of the reasons I went over to the "right side" as an adult. Never really talked politics with my parents. My dad rarely spoke about it, saying it was because he ran a retail business and didn't want to potentially offend some of his clientele. Looking back on it, probably a smart move, even in a state like Mass which, in those days, wasn't nearly as blue as it is today.
My mother, on the other hand, was a typical liberal hypocrite. She always claimed to vote for "the best candidate", but about 99% of them had a "D" after their names. And she had a particular blind spot to all things Kennedy, even after hearing some of the stories from my dad's customers about what tightwad bastards the entire family was.
The Dem party is practically a religion in Massachusetts.
