I think this whole thing is part of a plot to cause war or some protests in order to be able to declare a state of emergency allowing him to delay or cancel elections. If not the midterm, at least the next presidential elections. Because it is the only way he can stay in power.
The US had elections during their civil war in the 1800s, They had elections during WW2, major wars cannot even stop US elections legally. Doesn't mean he won't try, but it's not something he can do AFAIK.
"Not something he can do" is no longer a thing with this administration. All bets are off. Whatever logic you thought made sense, you can throw it away.
