Pat Quinn was anti-combine in the 80s and 90s, but he turned a blind eye to corruption once he became Lt. Governor under Blago and needed to ensure Blago won a second term so he'd stay on. He completely sold whatever was left of his soul to get the combine's blessing to run for Governor in own right. Now Quinn's such a combiner he rejected his OWN "Reform Committee" recommendations for transparency in this state.
Peter Fitzgerald was the last non-combine Senator for Illinois. Jack Ryan was asked to oppose him and flat out told the "powers that be" that he wouldn't challenge Fitzgerald in 2004 if Peter Fitzgerald wanted a second term. We saw the price he paid for straying from the combine's little "suggestion" after he eventually did run and win an open primary for that seat.
Quinn wasn’t as clean as we was made out to be. He was involved with some crap (I forget the details) back when was an aide to Walker.
