I see a lot of (justified) concern about mail in voting in the comments. I say Trump propose vote by appointment (maybe even a driveup system - if they can do it for Covid testing...). It could start early, people would have to show ID. It’d corral the fraud and could be done in a way that minimizes viral spread and makes people feel more secure (particularly the Independents Trump needs to win this thing).
The problem is that elections are held under state law not federal law. Each state determines its own election process. That’s why only Nebraska and Maine split their electors by congressional district and Colorado, Hawaii, Oregon, Utah and Washington hold all their elections by mail ballots.
What worries me the most is the Democrats now have eight more Governors running the elections in states than there were in 2016.
