I think this would be too heavy handed. Depending on how the supreme court case goes if it's ruled that mail in ballots cannot be counted after election day, then I think it would be trivial to quietly setup a scheme where mail from reliably blue postal codes is rerouted and delayed just enough to swing the outcomes. There are quite a few states that have mail in voting. That and intimidating "poll watchers" is probably enough.
