Outside of academia and the crunchy urban areas (Wellesley, Cambridge etc), New England/Massachusetts is not as liberal as you would think. I think voting blindly D and being a cultural liberal are not one in the same. I know many union types who vote straight D but who are culturally conservative and will welcome Tebow with open arms. I know the owner, Bob Kraft, loves Tebow and his faith. He has said it publicly.
wife is from there, still has family there and I lived for years there and yes it’s a liberal crap hole, hence the reason why we escaped the state.
I understand what you are getting at, I know many who vote D and yet have more social issues, not really about religion but because they find it sick and yes I;m talking about union guys.
Sadly many vote D because the union feeds them B/S , their family has always voted D or there are too many college kids who stay after school and transform the state.
