These are the roles all past presidents have assumed and the responsibilities they have borne, as leaders of us, the whole American public. Donald Trump has not risen to this opportunity nor accepted this burden, even once, because he has proved himself incapable of thinking or acting beyond the interests of me.

His callous, tweeted response to the deaths of nearly 50 people in the gun massacre at an Orlando nightclub when he was still campaigning for president—which began, “Appreciate the congrats for being right on radical Islamic terrorism”—prefigured the way he would respond to tragedies when he took office. After thousands of people died in the aftermath of Hurricane Maria in Puerto Rico, Trump awarded his administration, via tweet, “A Pluses for our recent hurricane work” and blamed “a totally incompetent Mayor of San Juan” for anything that had gone wrong. About Hurricane Harvey, in Houston, he seemed mainly to notice its “biggest ever!” size. After the deadliest gun massacre in American history, when one murderer in a hotel tower killed some 59 people and wounded hundreds in Las Vegas, Trump breezily said, “Look, we have a tragedy. [But] what happened is, in many ways, a miracle. The police department, they’ve done such an incredible job.”

The list of instances when Trump said the wrong thing could go on. The more important point is that he’s never said the right thing. Conceivably, weather might have kept him from paying his respects at the World War I battlefield in France last month. Nothing but narcissism kept him from driving the few miles from the White House to the Tomb of the Unknown Soldier, in Arlington, for the presidential duty of laying a wreath on Veterans Day. Any normal president would have recognized the responsibility to show up that comes with his uniquely privileged and powerful job. Trump manifestly did not.

Trump appears to have no moral, emotional, or intellectual ambit that extends more broadly than his own person, or some of his business interests, or perhaps some of his children. It’s not really fair to criticize him for something he cannot do. It would be like criticizing a person born without a larynx for not joining in song. This is how he is made, and how he is limited.

But this particular silence is deafening.
