The US presidency was supposed to be something different, something novel, compared with the fossilised monarchical rule that it supplanted after the American revolution. Born of Enlightenment theory, settler colonialism and 18th-century warfare, the US constitution gave the chief executive primarily an enforcement role, with the authority to lead armed forces in the event of foreign encroachment or domestic unrest but stripped of the capacity to legislate or issue judicial decisions. The architects of the new republic meant for the president to preside over a citizenry well-endowed with rights, not to rule over cowed subjects.
Chief executives from George Washington and Abraham Lincoln to Franklin Roosevelt and Ronald Reagan have been sorely tested by both the responsibilities and the limitations of the country’s highest, loneliest office. Through civil war, economic catastrophes, foreign misadventures, social upheavals and plagues, the presidency has endured, but it – and the 45 men who have occupied the job – has been moulded and often humbled by the promise and perils of the office.
