Fingers crossed here in WI. Although I'll note IL has a governor now promising to veto.
Unless the governor has a dead hooker or some kiddie porn in his past, and they're willing to spend it on CCW, you're going to need a margin of at least 2-3 legislators OVER a 66% supermajority in both houses when it comes time to override the veto. We've been to that rodeo twice here in WI. And presumably you don't just have the governor who'll be twisting arms, but the "Chigago machine" as well.
Keep in mind that many will support legislation only because they know the "fix is in", or, when promised a judgeship, or some non-elected six-figure state .gov job, will suddenly pull a John Kerry, and "were for it, before they were against it." Again, part of the rodeo we've attended before just to the north...
But that being said, I'd like to see IL and WI cross this finish line together. With Chicago being so problematic in areas of RKBA, and the third most populous city and metro region in the U.S.... on the national scene, IL would be a much bigger "win" for our side than WI would. Chicago would be the largest U.S. city to exist under a shall-issue CCW scheme, with all it's attendant opportunities to suppress crime, empower victims, and create incidents that put a national focus on the positive aspects of urban gun ownership and self-defense.
