I will say that social conservatism isn't a big factor here. New England believes in Frost's "good fences make good neighbors" statement. New Hampshire pretty much does, too. There are far fewer churches in the region-- even in Republican New Hampshire-- than in Southern states. The churches we do have are dry and non-controversial. Even Yankee catholic churches aren't as strict as varieties elsewhere.
So, on social issues, NH would be in the middle of the pack nationally on abortion, gay rights, Iraqi war, etc.?
Would Democrats be competitive if they ran as a fiscal conservative and a social liberal?
Also, isn't it true that NH is the only state that doesn't require a car driver or passenger to wear a seatbelt?
