With just weeks left in the legislative session, the AP is reporting that a vote in New York to legalize gay marriage is in trouble.

In a piece written by Michael Gormley titled Analysis: Gay Marriage In NY Hits Stumbling Blocks, Gormley quotes sources inside the Senate Republican conference saying they've seen no changed votes.

Of course, Republican votes in the Senate have always been the key to legalizing the institution. That's because the GOP controls the chamber, and while several Republican lawmakers have hinted that they might be open to supporting the measure, none has yet.

A 2009 effort to legalize gay marriage died in the Senate with no Republican support.

Of course, not all Democratic Senators support marriage equality either. The Senate's most vociferous opponent is Senator Ruben Diaz Sr. of the Bronx, a Democrat. Diaz, a Pentecostal minister, helmed a rally against the institution attended by thousands last weekend.

The campaign's most visible lawmakers – Governor Andrew Cuomo and Democratic Senator Thomas Duane – have also signaled that the proposed legislation might be in trouble.

On Tuesday, Cuomo said he wouldn't bring the legislation up for a vote unless he felt it would pass.

During a lobbing day in Albany for marriage equality, Duane said that even New York City Mayor Michael Bloomberg's influence hasn't won over any Republicans.

“It doesn't matter what the heartfelt support is,” said Duane, who is gay and carried the bill in 2009. “It cannot pass without Republican votes … yet none of them support my right to get married.”

Additionally, opponents are not simply holding the line. They have introduced a measure that would end the state's practice of recognizing the marriages of gay and lesbian couples performed in other states. The loophole allows gay couples from New York willing to travel to nearby Connecticut or Canada to legally marry.
