I don't understand what weight impeachment still holds in today's world. Trump was impeached twice - and? If Trump, in his second term, is supposed to be held liable through fear of impeachment for his actions, I'm afraid it won't be the counter-weight the Founding Fathers envisioned.
Let's add a 3-strikes and your out! law. Thrice impeached Presidents get thrown out of office and need to sit in jail for 3 turns unless they roll a double.
(Obviously a joke, but is joke is exactly what our Supreme Court is making out of our Constitutional Republic)
