It seems very likely that the reason why California is doing so much better than New York on coronavirus has nothing to do with a good tsar (mayor, governor, whatever). California might have had the virus much earlier and developed immunity by now.
Folks, I personally know 3 people who came back from California extremely sick with COVID-like symptoms in December – early January. Obviously, it’s very anecdotal. But look at the article at the link. It’s in the LA Times.
