what happened to vermont?

[WalterMitty]

once vermont was one of the most republican states in the union, now, it's the complete opposite.

maine, connecticut, oregon, and new jersey also fall into that category.

any ideas?  i have some, but i wish to hear some other opinions.

[WalterMitty]

wha tis the majority opinion here:

did vermont become more democratic because...

a.) the gop keeps moving to the right, which has turned off the more liberal 'yankee republicans'

b.) the influx of more liberal people from places like nyc.  (i do recall some kind of article about 'taking over vermont'...i think it appeared in playboy in the 60s?)

c.) all of the above.
