I wouldn't hold my breath.
Chicago runs Illinois. I'm from Chicago and can tell you the view of guns in Chicago is utterly schizophrenic. I actually know people there who BOTH support Chicago's gun laws AND illegally own guns. Chicago (and Illinois) is so used to corruption, oppression and having rights reduced to privileges bought and sold, that concealed carry will NEVER be voted in in Illinois. If Illinois EVER gets concealed carry, it will be by virtue of SCOTUS decision. That's the ONLY reason why Chicago and its suburbs no longer have their handgun bans.
