VA is actually safe Obama after this move.
How so? Isn't Virginia still an anti-gay state?
Seems questionable to me too, but it a matter of counting the noses that will flip. Many blacks who loathe gays and think they should be burned at the stake, to put it hyperbolically, will vote for Obama anyway. So maybe a case could be made. It would take quite a bit of work however. And oh, conversely, I'm not a potential Obama vote this time, even if he announces he's gay himself, going the other way. So some of those Reston folks who say thanks, what took you so long, won't be changing their vote either.
The issue isn't whether or not VA is pro or anti-gay... the issue is a) whether it's enough to stop them voting for Obama (if that was their intention) b) will support be strong enough in places to counter the likely drop off in others.
