Not enough, apparently, since the residents of California voted two times against gay marriage. the last vote, Prop 8 was a 52-46 defeat for gays! Quite remarkable considering San Francisco and Hollywood!
The reason this is even at the SC, is they couldn't get enough support to put yet another measure on the ballot!
I think they have oodles of procedural problems and the thing will get nowhere. We have an analogous situation in Kansas where the legislature set the school funding and the parents are suing for more.
