I am also suspicious of Kennedy - even if, as I predict they'll call it an individual right - because of the "reasonable suspicion" catch they've applied to other individual rights.
Down the road, I'm at least as suspicious of all the Judges as you are. Because D.C. is not a state, they can rule for individual right and yet not answer the question of whether it applies to state regulations through the 14th Amendment. Then I'll worry that the SCOTUS Conservatives - who favor the 10th Amen. (State Powers) over the 14th Amen - will $crew us.
I hate to to say this but I have to share your opinion, even some of the so-called originalists could disappoint us on this issue if they want to leave it to the states to decide. We know how states like NJ, NY, MA, IL, etc, have already decided.
