(3) More evidence that it's a hit job: the actual breakdown of current COVID cases is not red states vs. blue. It is urban vs. rural...as you'd expect on the upswing of a new conflagration. But the high-rates map is hugely correlated with urbanization, whereas "Trump country" is barely affected yet. That would be the real story, if there was one, which there is not. Have you seen stories on the crises in NYC and Long Island? Maybe I've missed them.
