The Worst President in History

President Donald Trump has long exulted in superlatives. The first. The best. The most. The greatest. “No president has ever done what I’ve done,” he boasts. “No president has ever even come close,” he says. But as his four years in office draw to an end, there’s only one title to which he can lay claim: Donald Trump is the worst president America has ever had.

In December 2019, he became the third president to be impeached. Last week, Trump entered a category all his own, becoming the first president to be impeached twice. But impeachment, which depends in part on the makeup of Congress, is not the most objective standard. What does being the worst president actually mean? And is there even any value, at the bitter end of a bad presidency, in spending energy on judging a pageant of failed presidencies?

It is helpful to think of the responsibilities of a president in terms of the two elements of the oath of office set forth in the Constitution. In the first part, presidents swear to “faithfully execute the Office of the President of the United States.” This is a pledge to properly perform the three jobs the presidency combines into one: head of state, head of government, and commander in chief. In the second part, they promise to “preserve, protect and defend the Constitution of the United States.”

Trump was a serial violator of his oath—as evidenced by his continual use of his office for personal financial gain—but focusing on three crucial ways in which he betrayed it helps clarify his singular historical status. First, he failed to put the national-security interests of the United States ahead of his own political needs. Second, in the face of a devastating pandemic, he was grossly derelict, unable or unwilling to marshal the requisite resources to save lives while actively encouraging public behavior that spread the disease. And third, held to account by voters for his failures, he refused to concede defeat and instead instigated an insurrection, stirring a mob that stormed the Capitol.

Many chief executives have failed, in one way or another, to live up to the demands of the job, or to competently discharge them. But historians now tend to agree that our worst presidents are those who fall short in the second part of their pledge, in some way endangering the Constitution. And if you want to understand why these three failures make Trump the worst of all our presidents, the place to begin is in the basement of the presidential rankings, where dwell his rivals for that singular dishonor.

For decades in the 20th century, many historians agreed that the title Trump has recently earned properly belonged to Warren G. Harding, a president they remembered. The journalist H. L. Mencken, master of the acidic bon mot, listened to Harding’s inaugural address
