I'd happily see him drop any pretense of a Presidential run and go away. But I do think that the charges are a witch hunt, meant to prevent him from winning another term. How that will turn out is anyone's guess. I don't even think it is necessary. His most ardent supporters will vote for him no matter what, but he has probably lost so much mainstream support that his only role would be to split the Republican vote. If he is completely removed from the picture, the 2024 election might be Biden vs DeSantis, and I think DeSantis wins that contest. Possibly by a landslide.
I thought Trump's political career was over after the "grab them by the pussy" remark, but he proved to be resilient. I think he did a lot better than he'll be remembered for, but at this point he's little better than Biden- a broken-down old man who should spend the rest of his days in a rocking chair on the porch, with a glass of lemonade in his hand. Not running a nation with massive military, industrial, and economic power that is coming to a crossroads that will determine its long-term future.
