It would be nice if that happened, but there's a fundamental discontinuity there: The state issues the marriage license in the first place, and marriage has always been generally considered a "state" thing. The federal government doesn't regulate the marriages themselves, so why should they regulate a given state's criteria for recognizing that marriage?

Don't get me wrong, I'd like to see this problem fixed, and the only way it'll get done is if the federal government puts its foot down. I just don't see how it can. When the republicans tried to get the opposite thing passed, it didn't work.

Edit: Oh wait I forgot about this one.
