I haven't read much about this ruling on DOMA, but a casual read suggests that the problem the court had with DOMA is that it interferes with the those states that want to define for themselves what marriage amounts to. So, right wing attempt to pick on homosexuals is struck down on the right wing principle that the states should have greater autonomy. I hope a few right wing heads explode over this one (here). If I didn't have work to do, I'd probably head to what's wrong with these people and read the comments. But, well, I have work to do. I know they must be suffering a bit tonight and I can take a small measure of comfort in that.
(As you might have guessed, the judge is one of those long hair Nixon appointees. Seriously, someone needs to do something about these out of control Republican appointed judges.)
