I've mentioned this issue before, but as Trump keeps trying various ways to stop mail ballots (whether through the latest edition of the SAVE Act or through Trump's executive order to block mail ballots from being delivered in states that won't give his administration full access to their voter rolls) no one is talking about the fact that two states vote almost entirely by mail: Washington and Oregon. If vote by mail ends, or even is severely restricted to just members of the military etc., then those two states would not be able to hold anything resembling an election in November.
Unless I'm missing something? That is possible. It is hard to figure out what the effects of, for example, the SAVE Act would be. There have been several different versions, and our national press is chronically allergic to explaining policy. A ton of ink is spilled over whether there are votes to break the filibuster, or machinations to attach the SAVE Act to some must-pass budgetary bill. But almost none of them ever get into the weeds to explain what the Act would do if it was passed.
