The constitution prohibits ex post facto prosecution.

Assuming that we continue to elect presidents, you need one to appoint an effective Attorney General (ie not Garland) and use these new king like powers of the executive to smash. The president was convicted of dozens of crimes, but nobody had the balls to throw him in jail.

You have to think about 2025 solutions. The die is cast, it isn’t 1995 anymore. Nobody is clutching their pearls because POTUS made a mess on an intern anymore. It’s a different environment and you’re going to have to have fistfights on the Senate floor if the congress is functioning.
