Trump demands that Comey be prosecuted. The US Attorney in Virginia, a seasoned professional, investigates the matter and concludes there is insufficient evidence for a successful prosecution. Trump then replaces him with a woman who served as his personal lawyer; she has never prosecuted a case in her life. With the clock ticking, the new US Attorney personally takes the case to a grand jury and secures an indictment. What could go wrong?
Just about everything. The Trump/James II analogy really applies here, except that Trump can’t rely on Judge Jeffreys to do his dirty work. Even without much knowledge of the merits of the case, I am willing to predict that it will be a spectacular fail sooner or later, and that Trump will deservedly take the blame.
