JAMES TARANTO: The Packers Can’t Beat the Lions: A law professor has trouble distinguishing the Supreme Court from the NFL. “Carrington’s political sense is even more defective than his legal understanding. FDR was unable to persuade Congress to enact a court-packing scheme even though his party had huge majorities in both houses of Congress and his legislative program–in sharp contrast to ObamaCare–was broadly popular and enjoyed bipartisan support on Capitol Hill. . . . A Democratic court-packing scheme, whether proffered this summer or in a hypothetical second Obama term, would be laughed right out of the Capitol.” Yes, I made the same point recently.
