Red and blue.

Betsy linked to the 2006 red/blue map of congressional districts.  Check it out here.  Also some neat cartograms, with technical details at the bottom.

I was struck by the appearance of Minnesota, my home state.  Minnesota is kind of interesting, as it has exactly one large urban area made of two neighboring midsized cities, one of which I occupy.  Look at that:  blue city, blue "outstate" (there are some small cities like Duluth, but otherwise it’s a lot of rural) — red suburbs.

Is this pattern as obvious anywhere else in the country?  Western Indiana is the only other place I see it.
