No staff shake-up would have prevented any of this from happening. It would have descended on a hapless White House staff like a superheated pyroclastic flow from a presidential Pinatubo. And it will continue to descend, week after grim week, until Trump leaves or is forced from office.

That is the Trump reality. A man with a deformed personality and a defective intellect runs a dysfunctional administration — a fact finally visible even to its most ardent admirers. Who could have seen that one coming? Who knew that character might be destiny?

To reread “The Flight 93 Election” today is to understand what has gone wrong not only with the Trump presidency, but also with so much of the conservative movement writ large. In a word, it’s become unhinged.

To imply, as Anton did, that Barack Obama, for all his shortcomings, was Ziad Jarrah, Flight 93’s lead hijacker, is vile. To suppose that we’d all be dead if Hillary Clinton, for all her flaws, had been elected is hallucinatory. To argue that the United States, for all its problems, was the equivalent of a doomed aircraft is absurd. To suggest that Donald Trump, a man who has sacrificed nothing in his life for anyone or anything, is the worthy moral heir to the Flight 93 passengers is a travesty.
