It seems I got ahead of events in my post last night. Chicago Public Radio clarified this morning what's going on in the General Assembly:

Before it even went to committee, legislators debated not gay marriage, but the process they’ll use to discuss the issue.

Republican State Sen. Dale Righter said it’s hard for the public to follow bills as they move around the Statehouse, and the issue shouldn’t be rushed.

Senators voted 28-24, in effect stalling the bill. But the gay marriage issue could still be addressed again Thursday. It comes as the chairman of the Illinois Republican Party said in a statement that he supports gay marriage while Cardinal Francis George of the Archdiocese of Chicago wrote a letter explaining why he opposes it and urging Catholics to actively fight it.

The Tribune has more:

Gay marriage is but one issue on a crowded agenda of the final days of the outgoing General Assembly. Lawmakers also are looking at pension reform, driver's licenses for illegal immigrants, gambling expansion and gun control before the reset button is hit when the new Legislature is sworn in Wednesday.

Given the political complexities, it will be a tall order for lawmakers to complete a comprehensive pension overhaul by the time the clock runs out. Same goes for chances of passing a major gambling expansion to meet Mayor Rahm Emanuel's desire to have a Chicago casino.

And Lt. Gov. Sheila Simon had a good response to the Cardinal's idiotic "legal fiction" canard: "Simon argued that adoption is similarly a "legal fiction" that helps citizens form a family unit — and one that she also supports."
