France conducted elections on the 15th March and 28th June.

It led to debates and criticisms but, looking at the infection numbers it does not seem to have have any negative effect, especially on the 28th June.

They took precautions at polling stations: Limited number of people inside at the same time, no entry without face covering and hands sanitiser for everyone on entry, no handshakes, everyone well apart from one another.

Anything that requires following the rules will fail in the Unites States.

Police at polling stations to enforce rules is also considered voter intimidation thanks to Jim Crow jackassery a century and a half ago, so that is also a no go. We are also super litigious.

We have had large in-person primary voter turnouts without resulting surges in COVID cases, so I think it isn't really a danger.
