In New York State, the battle for gay marriage came down to the wire in the Republican-controlled state senate. In the end, four Republican senators defied their party to back same-sex marriage, making New York state the sixth state in the US to allow same-sex marriage. President Barack Obama has been giving speeches to gay activists, but he still says he personally believes marriage is between a man and a woman. New York's Conservative Party has vowed to go after the Republicans who voted for gay marriage. But these four legislators have no doubt found a new source of support.
