Someone, please post the roll call.
I believe the Rats can still bring this up again until tomorrow.
According to the linked article at http://www.savecalifornia.com :

The vote in favor of AB19 to "make marriage gender neutral" was 37 to 36, which means it was 4 votes shy because a simple majority is required of the 80-member assembly.
Unfortunately, I don't know how to look up who actually voted for/against it. I know the sponsor of AB19 is Assemblyman Mark Leno.
