In 2003, during the George W. Bush administration, the columnist Charles Krauthammer coined the phrase “Bush Derangement Syndrome” to refer to some of the president’s more unhinged critics. It was funny, and given Krauthammer’s background — he was a medical doctor specializing in psychiatry — it had the ring of truth.

Now, the nation is in the fourth year of Trump Derangement Syndrome. And there are plenty of indications that the condition, already acute, has been made worse by the coronavirus crisis. Just Google “Trump” and “blood on his hands.”
