Diaz is only one of them. This goes back to when the Dems won the senate finally. Malcom Smith the current leader supports gay marriage, but the 3 dems (which would make the vote 29 - 33 against) made a big hooplah over supporting him for dem senate maj leader because of gay marriage. They did get a lot of flack over it though (of course it was more complicated than that). Overall though, the new senate maj leader supports gay marriage as well, and i guess it would depend on how much pressure we can put on the 3 democratic hold out senators of the state.
