Gregory Travis has done some interesting graphs comparing COVID-19 deaths and infections by county, splitting for Republican leaning and Democratic leaning counties. Not a perfect split, since many counties are close to 50%-50%, but even so, there are definite patterns.
I am very concerned about the unvaccinated in the approaching fall and winter. It could be much worse than the first wave, which occurred when COVID-19 wasn’t yet widespread and there were serious attempts to disrupt the spread. What will the reaction be when large numbers of willfully unvaccinated, who tend to oppose things like lockdowns anyway, start getting sick in large numbers?
