The one thing we have going for us that might make a difference in the fact that the administration of elections is up to the individual states. So there is very little the President can do, on his own. Even the recent Executive Order targeting elections only threatened to stop Federal funding. States can (and will!) fund elections on their own if they have to.
We also have never postponed a Federal election, the date is set by Federal law and it has gone off without a hitch, even through a Civil War and all the wars and pandemics since. So he can declare “Marshall” Law all he wants, but States are free to ignore him and hold elections anyway.
