New York and New Jersey could become the sixth and seventh states to legalize same-sex marriage.
New York's Governor David Paterson has asked Albany lawmakers to vote on the matter this week and some New Jersey lawmakers are pushing for a vote in the next few weeks.
NYC Councilwoman: We'll be Trail Blazers
Several New Yorkers gathered in Union Square Monday night to show their support for gay marriage.
"We will be trail blazers," vowed New York City Council speaker Christine Quinn. "We will get this done and we will have the most fabulous weddings."
In a rare mid-year address on Monday, Paterson urged lawmakers to legalize gay marriage, calling it "an issue that touches on the very core of our citizenship."
The New York State Assembly has already approved a gay marriage bill, thus taking the fight directly to the state senate.
But politicos disagree on whether there are enough votes to pass the bill - or even bring it to the floor.
"While some advocates of same-sex marriage are trying to force a vote on the issue, many moderate Republicans and conservative Democrats - or at least Democrats in conservative-leaning districts - are very reticent to bring the issue up facing an election next year," said Rev. Jason McGuire, legislative director of New Yorkers for Constitutional Freedoms.
Other Battleground States
Besides New York, New Jersey is this month's other hot battleground over marriage.
Governor-Elect Chris Christie says he'll veto any same-sex marriage bill. That's forcing gay marriage supporters to try and work a bill through in this month's lame duck session, before Christie takes office.
California is another state sure to be a major battleground for marriage in the next few years.
A federal lawsuit challenging the state's marriage amendment is set to go to trial in January.
Meanwhile, gay marriage supporters say they are planning to bring the issue back to the voters sometime in the near future.
