It's unconstitutional and would set a terrible precedent that even the most braindead liberal could admit would make the country look no more free than Uganda.

If you can impeach a private citizen that used to be POTUS, you can impeach ANY private citizen, and that's an incredibly scary thought, arbitrarily removing dissidents from either party's pool of viable candidates for an election.

This should be a clear cut abuse of power case if they ever proceeded to do it.
