I follow a lot of legal content and work in a legal field, but I am not a lawyer and this is just an opinion from the outside:
Trump has 2 wildcard advantages that make the outcome hard to predict.
1: this is being presided over by a judge who has shown incredible favorable bias towards him. Even with the circuit laser eyed on the case breathing down her neck to make sure she plays fair ball, there are simply a ton of areas where she can fuck the prosecution over and the circuit can't do shit. This is the structural nature of federal court. The only thing holding this back from happening is that it would cause such a massive national shit show her life might legitimately be in danger if she did this. (I don't not advocate violence In any way. But that kind of backlash would not surprise me or feel karmically unjust)
2: it only takes 1 juror. 1 trump fanatic to lie smoothly through jury selection, and then sink all charges by folding their arms. Now this feels unlikely just because the venn diagram overlap between "can make plans, lie smoothly, and stick to their guns through social pressure" and "Miami trump supporter" is very narrow. But it can still happen.
Other than this? Well intent, with someone like trump, who lies constantly for no reason about everything and doesn't talk to or listen to his lawyers, is actually a pain in the ass to prove. That being said, the evidenciary outline the case opened with indicates that they have genuinely strong evidence to prove intent, so I think he's sunk on this, especially when you consider he couldn't really get new lawyers in time for the trial start.
It's incredibly important to mention whenever discussing this: if he were literally any other person on earth he wouldn't be treated so nicely: skipped mugshot, no bail, speedy trial, etc. And he would absolutely go away for 20 to life. I say this as a professional, not a partisan.
