Come to think of it, has gay marriage ever survived a popular vote in the US? I can't think of one offhand, which is kind of disheartening.
No. Only one anti-gay ballot measure of any kind, a particularly draconian one in Arizona before that state slammed the dial as far right as it could go without breaking, has ever even failed.
Again, it will still probably get carried in Maine and Washington is more likely than not to be a squeaker, in which I think we still have a
slight but diminished edge. Either or both of those would be hugely important symbolic as well as practical victories considering the total lack of any previous victories of this kind. Minnesota might be saved by the fact that abstentions count as No votes on ballot questions there. I'm very depressed about Maryland, though.
