interesting how you've added to Section 4 of the 25th Amendment.  Here is your quote:  Or, by extension, by being so incompetent — or not-quite-right — that he or she poses a threat to the nation and must be removed immediately and replaced by the vice president.  The big question is who determines what is incompetent or not-quite-right?  Maybe you could be more specific about what those terms mean in your mind.  I'm sure the Supreme Court would be very interested in your take on what our constitution really means.  Our system is setup to specifically not allow people to redefine our laws to suit their preferences.  Funny how you're now concerned about things that pose a threat to the nation.  How about terrorism, unlimiited illegal immigration, or fake news?
