This is the precedent that Pelosi is creating. Impeachment going forward will be a political tool. The Founding Fathers warned us this might happen.
It's been political before. The problem now is that it is partisan. That means the next R president, if any, will be impeached too. The R party will continue to follow the Constitution and the D's will continue to shred it.
A bigger problem is the involvement of the deep state and the prior misuse of the intelligence apparatus against the opposing party and candidate. The Fouders cetainly never intended to have a federal or indeed global police force.
