"He's conservative in manner and conservative in approach," Mr. Tribe said. "He's a person who is cautious and careful, that's true. But he is also someone quite deeply immersed in the law, and he loves it. He believes in it as a discipline and pursues it in principle and not by way of politics."
Will he vote to overturn Roe v. Wade? Will he restrict government's ability to enforce environmental regulations? Does he find a right to privacy in the Constitution?
We can predict those answers with the same certitude of a prediction that a conservative former California governor named Earl Warren would reflect the philosophy of judicial restraint and inaction of the President who appointed him Chief Justice. Of course, that prediction would have been proven quite wrong by, among others, rulings such as Brown v. Board of Education.
Should we be concerned? Of course. But the country survived Roger Taney, as did the expansion of Constitutional liberties to those who Taney ruled were not fully human thus not citizens. John Roberts won't bring about the apocalypse. As one of John Robert's teachers at La Lumiere School (I taught there some years back) used to say to excitable teenage drama queens, "Remain calm."
