Always have been interested in what an Illinois map would look like in the year 2014. This is my best guess:
Chicago and its suburbs being the anchor for the majority "Yes" vote with some support in college towns, the quad cities, and the STL suburbs.
Gay marriage would definitely pass (stay legal) in Illinois, but I'm not at all sure the counties near St. Louis would vote for it. They might be Dem-leaning but don't the St. Louis suburbs have a heavy SoCon streak?
Somewhat so, but I think gay marriage is popular enough at this point that they would be on board. They are certainly not as blue dog as some of the rural Dem-leaning counties that I have marked in red on this map.
