If Oklahoma didn't go the nullification route, I doubt even Alabama will.
Alabama is already on the nullification route. I highly doubt they will suddenly change just because a few more justices tell them to do so.
Oops, forgot it's already legal in OK and they apparently fully complied, so scratch Fallin off my short list. And amazingly, there was no organized resistance to it in SC either. I really think this comes down to AL and KS. MS doesn't want this on their record after the horrific mess there 50 years ago.
