I think most people are lost in the weeds on this. First off this is completely unfair and disgusting and a true threat to the Republic. That said you have to remember who the real threat is and that is the Deep State even more than the Democrats. Thoughts and predictions:
1. While this is all pretty bogus, in the end Trump screwed himself by running his mouth. He can deflect and deny and talk about Biden all he wants but he also appears to have bragged about having Classified docs and they had military secrets. That's going to sink him with the public even if he somehow manages to avoid jail. Trump supporters forget that he has to win over voters.
2. There is more to come for Trump, this is only Round 2 of at least 4. The DC and GA Grand Juries will drop the hammer soon enough. Also witch hunts but Trump likely did stupid things there as well and will make things worse.
3. The goal here is to get foolish Republicans to think they are battling this by nominating Trump who has zero chance of winning. It's a double win because he will lose and they can get even more people to feel helpless to stop it.
4. The Biden stuff is sticking but it's a distraction. He's being setup as the Fall guy. I fully expect Biden to drop out, likely citing health reasons, and then be blamed for everything but it won't matter much because they guy likely won't live much longer. He will also likely pardon his son on the way out the door. Then the Dems just replace him with Newsom and you have a Newsom/Trump election with Trump dealing with 4 separate legal battles that have nothing to do with Newsom. Newsom wins.
5. The only way out of the trap is DeSantis. He has all the tools necessary to win and to fight this after he is elected. He's the only one of the current field with a chance. Even then he is in for a rough time but at least he has a chance.
