According to the linked article at http://www.savecalifornia.com :
http://www.signonsandiego.com/news/state/20050602-1935-ca-xgr-gaymarriage.html
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.
How to look up the roll call: savecalifornia.com
has a "statement" about AB 19 on its home page.
At the bottom of the statement is the roll call.
Thanks for the link. Much appreciated. One "Republican,"
Keith Richman, abstained instead of voting NO.
