@snood,
Reality is optional when in doubt, but usually annoying.
But this phase will come to a brutal end. It is easy to say untruth with impunity about things that are far away (Sweden) or in the distant future (the climate crisis) in the eyes of your voters. But when your neighbours, friends and relatives start to fall seriously ill or die, this contradiction cannot be resolved or pushed away by an extra dose of Fox News. (Hardcore conspiracy theorists perhaps excepted, because as usual they will find other explanations in which Trump is both hero and victim.)
Trump contributed most to the escalation with his usual reflexes: shutting things down ("It'll go away again, just stay calm, it'll go away again"), putting the blame on others ("foreign virus"), prohibiting entry from Europe (but not for Americans and travellers from countries where Trump owns golf courses), praising himself, creating confusion.
