Pierce Franklin - Franklin Pierce

The president is the central player in the American political order. That would seem to contradict the intentions of the Founding Fathers. Remembering the horrid example of the British monarchy, they invented a separation of powers in order, as Justice Brandeis later put it, to preclude the exercise of arbitrary power. Accordingly, they divided the government into three allegedly equal and coordinate branchesthe executive, the legislative, and the judiciary.

But a system based on the tripartite separation of powers has an inherent tendency toward inertia and stalemate. One of the three branches must take the initiative if the system is to move. The executive branch alone is structurally capable of taking that initiative. The Founders must have sensed this when they accepted Alexander Hamiltons proposition in the Seventieth Federalist that energy in the executive is a leading character in the definition of good government. They thus envisaged a strong presidentbut within an equally strong system of constitutional accountability. (The term imperial presidency arose in the 1970s to describe the situation when the balance between power and accountability is upset in favor of the executive.)

The American system of self-government thus comes to focus in the presidencythe vital place of action in the system, as Woodrow Wilson put it. Henry Adams, himself the great-grandson and grandson of presidents as well as the most brilliant of American historians, said that the American president resembles the commander of a ship at sea. He must have a helm to grasp, a course to steer, a port to seek. The men in the White House (thus far only men, alas) in steering their chosen courses have shaped our destiny as a nation.

Biography offers an easy education in American history, rendering the past more human, more vivid, more intimate, more accessible, more connected to ourselves. Biography reminds us that presidents are not supermen. They are human beings too, worrying about decisions, attending to wives and children, juggling balls in the air, and putting on their pants one leg at a time. Indeed, as Emerson contended, There is properly no history; only biography.

Presidents serve us as inspirations, and they also serve us as warnings. They provide bad examples as well as good. The nation, the Supreme Court has said, has no right to expect that it will always have wise and humane rulers, sincerely attached to the principles of the Constitution. Wicked men, ambitious of power, with hatred of liberty and contempt of law, may fill the place once occupied by Washington and Lincoln.

The men in the White House express the ideals and the values, the frailties and the flaws, of the voters who send them there. It is altogether natural that we should want to know more about the virtues and the vices of the fellows we have elected to govern us. As we know more about them, we will know more about ourselves. The French political philosopher Joseph de Maistre said, Every nation has the government it deserves.

At the start of the twenty-first century, forty-two men have made it to the Oval Office. (George W. Bush is counted our forty-third president, because Grover Cleveland, who served nonconsecutive terms, is counted twice.) Of the parade of presidents, a dozen or so lead the polls periodically conducted by historians and political scientists. What makes a great president?
