I am one of the people the OP is talking about who doesn’t believe Trump will spend a day in jail, even if convicted of all of these felony counts in NY. The reason is simple: Trump has gotten away with things over and over and over and over again with minimal consequences, and I think he’s going to do it again.
Like it or not, he is often (not always) being treated differently from other defendants in his various cases. There are a variety of different reasons for this, including one corrupt/incompetent judge (Cannon). But the biggest reason is that he’s the former President of the United States and the courts are walking on eggshells around this fact. Take, for example, the January 6 election interference case. He’s been allowed to appeal that case to two higher courts, including SCOTUS, before the case even goes to trial, never mind a verdict. How many defendants get to do that?
Similarly, how many defendants get to repeatedly and publicly disparage judges, district attorneys, and their families in the harshest terms with little consequence? Sure, he’s had to pay some tiny fines, but those fines are like being fined a penny to a normal person. Any non-Trump individual who tried that shit would have seen a jail cell, even if just for a day. But Judge Merchan has said, on the record and in court, that he doesn’t want to do that. From the NY Times:
The judge said that he understood “the magnitude of such a decision” and that jailing Mr. Trump would be a last resort. He noted: “You are the former president of the United States, and possibly the next president as well.”
A normal defendant would not get that kind of deference. The same will be true of his sentence, if he is convicted. Because of his status and the explosiveness of jailing a former president/current candidate, as well as the non-violent nature of the charges, the court will go easy on him.
Can I prove that? No. Am I a lawyer? No. Could I be utterly wrong about that? Yes. But I still think it’s the most likely outcome, and I believe those folks like the OP who think he will be sentenced like any normal convicted felon are whistling past the graveyard.
