It's not whether he legally could theoretically go to jail. It's whether that is likely to happen in a US judicial system that is exceptionally biased in favor of rich, powerful individuals. Good luck with that.
And let's not pretend there is any real precedent here because there isn't. Almost all these cases are entirely unprecedented and untested legally. 34 of those charges are related to Stormy Daniels, a case that seems very unlikely to end in prison time even if its theoretically possible. Another 40 related to the classified documents case which doesn't seem very likely to end in jail time either because the judge is a Trumper. In the Georgia case, he is almost certainly going to claim 1st Amendment and that will be a strong defense whether we like it or not. Jan. 6, I have a hard time imagining him getting convicted. Even if he got convicted in one or more of these, you know he is appealing all the way to that conservative SC, and even if it got decided before the 2024 election, which I don't think is very likely either, that SC will just side with Trump, zero confidence in that fecked up majority doing the right thing.
