I guess it's time to face facts.

Neither the Constitution's impeachment mechanism (except for federal judges) nor section 4 of the 25th Amendment (except perhaps for comas) really works.

I mean, we've now had two presidential impeachment "trials" in which a grand total of zero witnesses were called, and which will have resulted in acquittals, despite overwhelming evidence of guilt.

And for four years, we had a president who, by virtue of his psychological disorders, would have been removed from virtually any other job of significant responsibility.

So these mechanisms just don't work. Not because they don't make sense on paper, but because too many people charged with carrying them out lacked courage, principle, or both.

I've always had a slight preference for Westminster-style government, and now I have no doubt.
