ALBANY, N.Y. - Voters in California just banned same-sex marriage in a tight referendum, and Tuesday's U.S. election has opened the door for the same debate to now start in New York.

With control of the state Senate about to shift away from Republicans, it removes one clear obstacle to legalizing gay marriage in New York.

But opponents still aren't conceding anything yet and advocates say they have work to do.

In fact, a Senate power shift isn't even a guarantee because four Democrats are considering an alliance with the GOP.

That would swing the 32-30 majority back to Republicans.

But even in Democratic control, those for and against the bill say the votes still might not be there.
