It may strike you as deranged that a sitting president facing a pandemic has busied himself attacking journalists, political opponents, television news hosts and late-night comedians — even deriding a former president who merely called for empathy and unity in response to the virus. It may strike you as nuts that Trump bragged about his supposed Facebook ranking in the middle of a virus task-force briefing, asserted that millions would have died were it not for him, boasted that “the ‘Ratings’ of my News Conferences etc.” were driving “the Lamestream Media . . . CRAZY,” and floated bogus miracle cures, including suggesting that scientists consider injecting humans with household disinfectants such as Clorox.
