Senate President John Cullerton has been telling some of his members for weeks that he was resigned to an overtime session. The General Assembly likely wouldn't be able to adjourn by the scheduled May 31 deadline, he said. There was just no getting around it, so people should just accept that fact and move forward.
But not long ago, Cullerton reportedly came to the conclusion that if the spring session did go into overtime, Republicans would likely keep everyone bottled up in Springfield all summer long. So now his focus is on getting everybody out of town by the end of May.
May 31 is an important deadline because all bills voted on after that date require a three-fifths majority to pass. That means no budget can be approved, no Medicaid solution can be found, no pension systems can be reformed without supermajorities.
The Democrats control both legislative chambers, but they don't have three-fifths. They're seven votes shy in the House and one vote short in the Senate. One vote may not seem like a lot, but the partisanship can sometimes get so intense in the General Assembly these days that one vote might as well be a hundred.
