I could see it as early as 2032, but that's really pushing it. More likely around 2036-2044. By that point most of the Boomers will be either a) dead or b) too decrepit/senile to make it to the polls.
Really, I think it'll be the 2090's, just because when I was in high school at my school everyone made fun of gay people. It's kinda sad.
I doubt it, attitudes have changed very rapidly. Even among the general population, gay marriage has 39-44% support by now among the general population (>70% for 18-35 year olds) in addition to high support for opening the military and anti-discrimination laws. That's pretty remarkable considering bi/homosexuality was a 'mental illness' into the '70s. If we keep up the current pace gay marriage will probably be legal and treated the same was a 'inter racial' marriage in another 15-20 years. And considering what's going in Rhode Island (and elsewhere) I'd say openly gay governors aren't out of the question for the Northeast and West Coast this decade...
