> and have the might of the U.S. military brass behind him
Would he, though? I know the top US military brass have gone through some changes during this administration, but if the military sees a lawful impeachment and lawful conviction, I think enough would refuse (clearly illegal) orders to keep Trump in the White House.
Honestly I'd be more worried about the loyalists at the top of the FBI, US Marshals, Secret Service, etc.
Either way, it's incredibly improbable that Democrats will control a supermajority of the Senate next year (or, failing that, have enough Republican support to convict), so we probably won't have to find out what happens in this scenario.
> I think enough would refuse (clearly illegal) orders
The military executes clearly illegal orders to attack civilians on speedboats in the Pacific a couple of times a week. Not infrequently, they also kill the occupants when they are surrendering.
People’s opinions only matter so far as they have to care about elections. Not having to worry about those sorts of nuisances is entirely the plan and they are frighteningly near succeeding at it.
If you can’t tell, I am not hopeful.
