Great news from Illinois:

The Democratic-led Senate delivered a Valentine’s Day victory to gay and lesbian couples today, passing legislation for the first time that chicago_cityscape_hancock_tower-would allow same-sex marriage in Illinois.

The gay marriage measure now goes to the House, where the fight is expected to be tougher. Gov. Pat Quinn is expected to sign the bill if it reaches his desk.

The 34-21-2 Senate vote represents a turnaround of sorts after advocates unsuccessfully sought to push a gay marriage bill through last month’s lame-duck legislative session. Supporters vowed to try again quickly with a new General Assembly that featured even more Democratic seats in both chambers.

Marriage equality in Illinois would be huge, because it would be the second Midwest state to allow gay couples to wed. This would be a significant boost to the fight, as well as include America’s third largest city.
