“[The Framers of the US Constitution] shrank from placing sovereign power anywhere. They feared that it would generate tyranny; George III had been a tyrant to them, and come what might, they would not make a George III. Accredited theories said that the English Constitution divided the sovereign authority, and in imitation the Americans split up theirs. The result is seen now. At the critical moment of their history [after the Civil War] there is no ready, deciding power…. The President wants one course, and has power to prevent any other; the Congress wants another course, and has power to prevent any other. The splitting of sovereignty into many parts amounts to there being no sovereign.”
