Here is today's screenshot of the rolling poll average on
HuffPo. The interesting feature is the widening error bands which indicates less confidence that either candidate is actually in the lead.
The wildcard is how much anti-Quinn vote will go to the Libertarian as a protest against the negative advertising. Advertising for the independent Cohen in 2010 was a key factor in Quinn's win over Brady when compared to Kirk's success in the concurrent Senate race. Union money is now going to the Libertarian Grimm to push conservative voters away from Rauner due to his moderate stance on key social issues. I have received two push polls backing Grimm from independent polling firms that generally poll for Dems in the last week and a half, and both polls stressed social conservative issues.
