So why didn’t Justice Anthony Kennedy, the traditional swing vote who wrote the majority opinion on DOMA with the court’s four liberals, take that step? Why did he avoid doing the full Roe — nationalizing the procedure in question and declaring the subject now closed? I suspect he thought it would be a bridge too far. At least for today.

But he knows that the double rationale underlying his DOMA opinion has planted the seed for going Roe next time. It was prudence, not logic, that stayed his hand. “The only thing that will ‘confine’ the Court’s holding,” wrote dissenting Justice Antonin Scalia with a bit less delicacy, “is its sense of what it can get away with.” Next case — Kennedy & Co. go all the way.
