The United States Constitution rests on a handful of closely related premises. (Let’s call them “Madisonian.”) First: the Constitution has to serve the interests of citizens, not politicians and especially not state politicians. For an emphatic statement see Federalist 45 (To appreciate the depth of Madison’s conviction on this point, note that the verbal bombast in 45 is out of character for him. Even his letters to Dolley sound like they were written by her accountant.) Second: the Constitution has to make politics possible and discipline it against factional abuse. For the general theory see Federalist 10. Third, the Constitution has to ensure stability, both in the sense of institutional durability and of preventing political hyperactivity. For the perils of a “mutable government” see Federalist 62. Now invert the premises. First: the Constitution must protect the “states as states”—that is, their political elites and hangers-on. Second: the Constitution should facilitate interest group politics. Third: the Constitution should be democratic (and since the demos is fickle, the Constitution should be unstable). There you have the actual Constitution, upside-down. Get used to it: it’s the New Deal Constitution under which we live.
