Illinois Governor Pat Quinn on Wednesday said he will help build a majority for a proposed gay marriage bill.

Last week, openly gay Representatives Greg Harris, Deb Mell and Kelly Cassidy introduced a measure that seeks to make Illinois the eighth state to legalize gay marriage.

Quinn, who last year strongly backed efforts to approve a civil unions bill, was sounding less confident in his support for marriage equality when he told the AP earlier this week that he wanted to study the issues surrounding the bill before he makes a decision.

But during an interview with WBEZ Radio's Steve Edwards, Quinn made it clear that he backs the measure.

“Well, I was the one who got civil unions passed. Because the sponsor of the bill in the House – this was about a year or so ago – came to me, had 57 votes. And there were 4 people, he had to get 3 of the 4 to vote yes in the House. … I talked to all 4 of those members, they all voted yes and the bill passed.”

“You know in a Democracy, you got to build a majority. So any development off of civil unions – we have 3,700 civil unions that have been performed so far in Illinois in 90 of our 102 counties. You know, it's a democracy and you have to build majorities.”

When pressed by Edwards, Quinn said that he looks “forward to working with the advocates on this issue to build a majority.”

“You gotta work with members from all parts of Illinois, every part of our state, some parts are more liberal than others, and ultimately we'll get to Heaven.”
