"This would give the creature a chance to claim that a military coup is taking place, declare martial law, and then refuse to give up his office for "the good of the country.""
I seem to recall the DUmmies, in December 2016 and early January 2017, demanding that Saint Obama do those very things: Stay in office past his term limits "For the good of the country," throw out the election results on the grounds that a candidate the DUmmies didn't like won, and declare martial law in order to suppress any who might oppose him doing those things.
I guess those things would only be wrong if a Republican did them.
