Ummmmm, there's one reason most of the counties with the most new deaths are south of the Tehachapis that DU-folk don't want to hear. Expats living in Mexico and green card holders who are desperately sick with Covid-19 are being brought from overwhelmed Mexican hospitals in cities just south of the border to hospitals in SoCal. Another contributor in SoCal counties and some Bay Area counties, probably, is the protests, where many were in close proximity, shouting, and not wearing masks.
I don't mind the expats and green card holders coming to CA hospitals. They are doing so legally. However I do think it wrong to include them in the stats counties and the Goobernor supposedly use to determine degrees of shutdown.
