American sovereignty resides in the American people, not in the American state, still less in the person of the chief executive, and the organ most closely representative of the people is the one whose members we call, not coincidentally, representatives. We are a nation under law, a nation of laws, a nation with equality under the law, etc., which necessarily means a nation under lawmakers — not a nation under an elected and term-limited pharaoh. It is the role of Congress to decide what the federal government is to do, and it is the role of the president to get it done. The president is a servant, not a master.
. . .
While we are thinking about who should be entrusted with the awesome powers of the American presidency, perhaps we should think just a little bit about whether those powers are a bit too awesome, and about whether the presidency should be somewhat reduced to something closer to its original constitutional conception. Calvin Coolidge could afford to be a modest president, because he occupied a much more modest presidency. Before you decide what kind of president you want in 2016, think about what kind of presidency you want in 2016, and thereafter.
