On April 29th, Donald Trump will have occupied the Oval Office for a hundred days. For most people, the luxury of living in a relatively stable democracy is the luxury of not following politics with a nerve-racked constancy. Trump does not afford this. His Presidency has become the demoralizing daily obsession of anyone concerned with global security, the vitality of the natural world, the national health, constitutionalism, civil rights, criminal justice, a free press, science, public education, and the distinction between fact and its opposite. The hundred-day marker is never an entirely reliable indicator of a four-year term, but it’s worth remembering that Franklin Roosevelt and Barack Obama were among those who came to office at a moment of national crisis and had the discipline, the preparation, and the rigor to set an entirely new course. Impulsive, egocentric, and mendacious, Trump has, in the same span, set fire to the integrity of his office.
