Great Map. My one question is how come there is so much red in Wisconsin while Minnesota seems far more blue. Western Wisconsin is pretty rural and white so it seems odds it went so strongly for Obama. New England is also went heavily for Obama, but this region has always been quite liberal compared to elsewhere in the US. As for Pennsylvania, no surprise, it is quite polarized between the urban and rural areas. Even New York seems to have a fair bit of blue, although looking at the county by county results it seems most counties that voted for McCain only went for him narrowly, while New York City went massively for Obama, so there was no way McCain was going to overcome Obama's strength in New York City unless he got somewhere in the neighbourhood of 2/3 of the vote in upstate New York.
Fundies in the Minneapolis suburbs/exurbs. Compare to the area around Milwaukee in eastern Wisconsin. Western Wisconsin is more like the Duluth area in northeastern Minnesota. Rural whites in the Democratic areas of Wisconsin and Minnesota are Scandinavians, mostly, your traditional mainline Protestant progressives. (Capital P Progressives, too, in both the US and Canada historically.)
Also, Obama won New York minus New York City (and Long Island, but it's less Democratic than the remainder of the state as a whole) with about 55% of the vote, so upstate New York is solidly Democratic. You could take out the entire NYC MSA, and it still would be solidly Democratic.
