Wouldn’t the real last card be organizing & mounting a full blown insurrection? Not like the first attempt where he could try to keep his hands relatively clean of it, as he’s tried to do in a number of other criminal schemes related to his businesses.

I doubt he'd be capable of orchestrating that. he threw his insurrectionists under the bus last time by inciting them and then not pardoning them; Trumpers willing to do such a thing are in or going to prison. Makes it hard to incentivize the next batch.

He's lost support in the military. Can you imagine him trying to lead troops like a general? It would be the shortest coup ever. He'd probably change enemy troop locations with a sharpie because he doesn't like where they are.

Trump is good at spewing vile rhetoric, he's not competent or popular enough to carry out a successful violent insurrection.
