To complicate matters, the Fox River Valley belt has a dovish streak (48'er Germans), which is my guess as to why that area trended so heavily to Obama. I am not sure how well Rick will play there given his "bellicosity."
The "Scandanavian" belt as it is characterized on the other side of the state by the way trended to McCain.
The most likely reason for the trend had to do with mccain spending alot more on media in MSP and Duluth markets.
Also the Scandinavian belt gos further south then you imply.
