Being part Scandanavian, I wouldn't say Scandanavians are socially liberal at all. Some maybe, but many are also very traditional and socially conservative. They are much more likely to be economically liberal than socially liberal in my experience.
Yep. This is true. Michigan northern peninsula has huge Finnish-American population (38 % in one county which name I have forgotten) and most counties votes Republicans.
Most Finns who went to America were from Pohjanmaa region which is most religious and conservative area in my country.
