No, I didn't mean that no one can have a democracy without an impeachment process--only that the U.S. can't have one if impeachment is going to become unused and archaic (which has been the Republicans' plan ever since they deliberately discredited the mere idea of impeachment as "too divisive" and "bad for the country" by their misuse of it against Clinton).  No other institution in the U.S. is empowered to stand up against the President if Congress won't.  (The Supreme Court can only do it piecemeal, if someone sues, if the case reaches the Supreme Court, and if the Court sides against the President--but it can't remove a President.)  And if Congress won't stand up . . .
