Again, there's nothing in case law, history, or any statement of the founders that even SUGGESTS that the Founders ever supported a blanket immunity from all law if someone decides to run for any office. Including president.
There's strong evidence that the Founders believed in law and order, constitutional protections, probable cause and speedy trials. All of which Trump has been afforded.
The Founders would do what MAGA refuses to do: Look at the evidence. If the evidence justifies the charges, then the Founders would be fine with it, in my opinion.
And the evidence in this case absolutely does.
