But first you have to have months of. "Something big is gonna happen!" Then all those wanting to go to jail will self choose and head for the ellipse.

That's a very different scenario than convincing actual military officers - in Seal Team 6 and above them all the way up the chain of command - to commit hardcore premeditated felonies. Not a bunch of idiots getting swept up in the moment.

As commonone recognized, this is a silly scenario - the number of "normies" that would have to be involved in a Seal Team 6 operation on U.S. soil is rather large, and none of them would be immune from criminal charges (even if you stipulated that the President would be, and I don't). Plus, the attack on the target would (in this hypothetical) take place within a U.S. State - which has its own criminal justice system and its own prosecutors and police force. No one can be pardoned for state crimes - so participating in a hit against Gavin Newsom would buy you a life in a California prison, even if Trump pardoned you for federal crimes.

This isn't normalizing Trump. He's a vile, egotistical narcissist who would love to play-act at being a dictator for a while. But he doesn't have a dictatorship to do it in. In a true dictatorship, you don't have a politically powerful opposition party that holds positions of real authority all across the country. Even if Democrats lose control of the House and Senate, those folks still have significant political power. And we have a country with States - political bodies that are not merely subdivisions of the federal government, but that are headed by sovereign governments with their own police powers - half of which are run by Democratic governors or have a Democratically controlled legislature.

So someone like Trump can't just muse aloud that he wishes Gavin Newsom would disappear, leading to him having a horrible end that has no consequences. Because unlike somewhere with a real dictatorship, there's lots of people who would care about that, and who have the power to make everyone involved pay for that. You can't have a dictatorship without fundamentally restructuring not just the federal government, but the state governments and their relationship to the federal government is well. And Trump is far to lazy to undertake anything like that.
