There was never a shadow of a doubt. In the plethora of opinions generated by these three cases, there is not a single one authored by Ruth Bader Ginsburg, Stephen Breyer, Elena Kagan, or Sonia Sotomayor. There was no need. They are the Left’s voting bloc. There was a better chance that the sun would not rise this morning than that any of them would wander off the reservation.

How can that be? Jurisprudence is complex. Supple minds, however likeminded, will often diverge, sometimes dramatically, on principles of constitutional adjudication, canons of statutory construction, murky separation-of-powers boundaries, the etymology of language, and much else. Witness, for example, the spirited debate between the Court’s two originalists, Scalia and Clarence Thomas, over a statute that, in defiance of Obama policy, treats Jerusalem as sovereign Israeli territory.

But not the Court’s lefties, not on the major cases.

And it is not so much that they move in lockstep. It is that no one expects them to do anything but move in lockstep — not their fellow justices, not the political branches, and certainly not the commentariat, right or left.
