Like I said, I don't care what he thinks about schools reopening. This is a local decision and based on their unique situations, some will and some won't. As it should be.
Regarding the elections, these have national ramifications and involve both local and national control and concerns. Here's an article that attempts to grade each of the states for mail in voting (pandemic proof voting). Some states, like CO are set up well. Other states aren't.
A paragraph in the article I found interesting and concerning.
According to a recent CNN report, “Experts say black voters are less likely to have had experience with absentee voting processes and are less likely to trust the government institutions to handle their votes in the mail.” As has become clear from the primary elections held so far, the transition problems as we move from in-person voting to voting from home have a disproportionate effect on communities of color. Recent scandals such as the Republican voter fraud scandal in the 2018 race in the 9th congressional district of North Carolina, which effectively destroyed absentee ballot requests among Democratic voters and especially voters of color, reinforces that skepticism among Black voters.
