I'm not so sure that Rauner is DOA for 2018. From what I've seen and heard, Madigan is being blamed for the budged impasse as much as he is. If Rauner runs for reelection, he can run on this and attack Madigan as leading a "do-nothing" legislature, a la Truman 1948. If he does that then his chances at reelection are very good.
In 2006, Jennifer Granholm did the same thing here in Michigan. She recognized that more people blamed Bush for Michigan's sour economy than her, and she played it to her advantage, winning reelection handily. I suspect that Rauner will win reelection in much the same way.
It's a shame IL has gone from having one of the best Governors to one of the worst. Another sad reminder that the People's Pat would be doing much better than this amateur.
Oh, yes. High taxes and big spending did such great things for Illinois.
