San Jose isn't going to be the problem. It's Bakersfield. It's Visalia. It's Stockton. It's all of the larger towns in more conservative areas that represent the Yes on 8 vote.
Worse still, apparently Utah Mormons think it's their business to pump tons of money into California's Yes on 8. I swear to Mormon God, when it comes up for a vote there, expect my money to flood into their state to support gay rights. It's disgusting that they think they get a say in what goes in the California Constitution.
Edit: BTW, it's not too late to donate and
volunteer. I've been volunteering quite a bit at a local field office, and I've donated an embarrassing amount. The wonderful thing is that the majority of volunteers aren't even gay (like me).
