NOM Chairman Maggie Gallagher in the Associated Press on the possibility of a 2012 marriage vote in Maine:

The National Organization for Marriage, which opposes gay marriage, isn't saying how much money would be needed to get out its message. But Maggie Gallagher, NOM's chairman and co-founder, said raising money for Maine wouldn't be a problem. The organization plans to raise $20 million this year in U.S.

"We've won 31 out of 31 times when this has been taken to the state. We'd be optimistic about winning again if they want to put Maine through another campaign," Gallagher said.

Maine voters in 2009 overturned a bill passed by the Legislature that would have legalized the practice. Thirty other states have passed amendments banning gay marriage.

Last month, gay marriage advocates announced that they'd be gathering signatures necessary to put the measure to a state vote again in Maine.
