We're getting to the point where Cook is one sided enough that a Democrat can win statewide narrowly by just winning that one county. Pat Quinn basically did it in 2010.
Most definitely. I still think the layout is interesting, though. Illinois has been compared to being a mini USA in the idea that it has a little bit of everything, and so you are able to see the southern Democrats down in Little Egypt going from Dem to Republican, the Midwestern Republicans in the central part of the state holding their ground, the suburbs becoming more Democrat, and the city putting up big Democrat margins as usual.
