From the NY Times:
Passage of same-sex marriage here followed a daunting run of defeats in other states where voters barred same-sex marriage by legislative action, constitutional amendment or referendum. Just five states currently permit same-sex marriage: Connecticut, Iowa, Massachusetts, New Hampshire and Vermont, as well as the District of Columbia.
At around 10:30 p.m., moments after the vote was announced, Mr. Cuomo strode onto the Senate floor to wave at cheering supporters who had crowded into the galleries to watch. Trailed by two of his daughters, the governor greeted lawmakers, and paused to single out those Republicans who had defied the majority of their party to support the marriage bill.
“How do you feel?” he asked Senator James S. Alesi, a suburban Rochester Republican who voted against the measure in 2009 and was the first to break party ranks this year. “Feels good, doesn’t it?”
The approval of same-sex marriage represented a reversal of fortune for gay-rights advocates, who just two years ago suffered a humiliating defeat when a same-sex marriage bill was easily rejected by the Senate, which was then controlled by Democrats. This year, with the Senate controlled by Republicans, the odds against passage of same-sex marriage appeared long.
