Yes, urban areas trend liberal for several reasons, probably, but I favor the one that says simply living in close proximity to so many people requires it of us. If so, then encouraging more urban centers throughout the state would tilt Minnesota toward the blue. If growth is concentrated only in the Twin Cities, then growth is problematic. We are trying to grow denser, but that's hard because it usually displaces somebody first.

I also favor Minnesota joining Canada when the USA falls apart, so don't pay my opinions any mind. ;)
