The New York State Senate just voted against legalizing same-sex marriage in a 34-28 vote.  It had previously passes the NY Assembly 88-51.

New York would have become the sixth state, and the most populous, to allow same-sex couples to get married. And it would have been the first to grant full marriage rights from a standing start, without having first granted interim rights such as civil unions.

Only one other state, New Hampshire, has approved gay marriage by action of the legislature. The others — Massachusetts, Vermont, Connecticut, and Iowa — have done so primarily by court action.

UPDATE —  Nice speech from NY Senator Diane Savino from Staten Island (give a chance):

Only one senator had the balls to explain why he was voting "no", saying that not only were all major religions against same sex marriage, but so were the vast majority of NY voters.  Except that as he was uttering those words, a Marist poll of NY voters on the subject was released.  And NY voters actually favor SSM.
