Not specific to any one case, but in general, I think he’s conceding that he will be found guilty of committing at least one felony, and very likely more, and that he will have little to no basis for a winning appeal when all is said and done. That is, I think realistically he recognizes (despite his frequent public pronouncements to the contrary) that he is headed for a long, long term in some sort of confinement. (Probably home confinement, in my view, but very unpleasant from Trump’s perspective at best.)
Which is why he’s mouthing off, in interviews and public speeches, the way he is. Well, also because he’s a born blabbermouth, but not completely. He has nothing to lose, and one thing to gain, by mouthing off: he gains sympathy from those inclined to give it to him. (Also money, but that’s just Trump doing Trump.) He’s decided that, legally, he’s screwed. Too many cases, too much evidence, to hope to skate on everything, so he’s betting all his chips that he’ll eke out a win in the Electoral College in 2024, and then self-pardon his way to freedom. That’s his strategy.
I put it at something like 5-to-1 against, maybe 10-to-1, but one hell of a lot better than his chances of being found not guilty of all the felony charges he will face in the next two or three years. The Presidency is his only realistic shot at beating the raps, and he’s going all in on that shot.
So all this talk about mounting particular defenses in specific cases is nonsense. He’ll do it, sure, or his lawyers will, but it’s all a distraction: judges, case law, constitutional interpretation, venue, voir dire—none of it is relevant to him. He is going to lose and lose bigtime—this is ALL a race against the clock, November 2024, and if the big enchilada escapes his grasp, then (to paraphrase Bill Barr and mix my culinary metaphors in the process) he is toast.
