What the most-vaccinated Trump counties have in common

As I wrote on Thursday, there are a lot of reasons for this, the most important being that large cities have lots of people, including many who voted for Trump. When we’re talking about large populations of unvaccinated people, though, this is important, particularly because cities also tend to exhibit a great deal of partisan and racial sorting. In other words, in those cities with lots of unvaccinated people, it’s fair to assume that the unvaccinated are not evenly distributed.
