This is really a guessing game. There are, obviously, nine votes we have to predict. I'd be more than a little surprised if any of the four "moderates" on the Court -- Ginsburg, Breyer, Souter, and Stevens -- would vote to uphold the D.C. Circuit. So that means we have to predict the five "conservatives." I think it's quite likely that Scalia and Thomas would vote to uphold the Circuit, and I think there's some reason to think that Alito might as well. Roberts has no known track record on the Second Amendment. Kennedy, as always, could turn out to be the person in the middle.
