What do you think of the point I made in post #17? When I think of the great Patriots that came from Massachusetts (Calvin Coolige rose to prominence there and, of course Charles Sumner), it's appalling that the state has, as a whole, become so leftist.
I think that Southern DemonRATS who were left jobless during the FDR era moved into your state and drove it leftward. The South was impoverished due to Roosevelt's anti-business policies. Although the north suffered during his regime, there were enough job opportunities that leftist Southerners migrated north. The upside is that Dixie became Conservative as the DemonRATS fled but their presence led to the evolution of New England into liberalism. Is that a plausible theory to you?
The liberal universities did the most damage here. But politically, things were controlled by the Kennedy machine, especially Ted. He knew exactly what levers to pull an when. He and the machine halted the advance of any republican who may be a threat in the future, cementing that stranglehold. And this style and attitude spread to the different states. It was all the intellectual New Dealers the colleges produced combined with shrewd politics that turned New England.
