The President of the United States got up this morning, watched Fox And Friends do a segment on his mental health, and used his Twitter thumbs to give the world a textbook example of the Dunning Kruger effect (screenshot added in case his tweets are deleted later):

Now that Russian collusion, after one year of intense study, has proven to be a total hoax on the American public, the Democrats and their lapdogs, the Fake News Mainstream Media, are taking out the old Ronald Reagan playbook and screaming mental stability and intelligence…..

….Actually, throughout my life, my two greatest assets have been mental stability and being, like, really smart. Crooked Hillary Clinton also played these cards very hard and, as everyone knows, went down in flames. I went from VERY successful businessman, to top T.V. Star…..

….to President of the United States (on my first try). I think that would qualify as not smart, but genius….and a very stable genius at that!

No stable genius has ever bragged about what a stable genius they were. No smart person would try to convince the world of their high IQ by using poor punctuation and 4th grade vocabulary while using “like” as a filler word in text.
No one with an ounce of historical awareness would argue that they retained their mental acuity by comparing himself to the Alzheimers-afflicted Ronald Reagan. No one who understood his legal peril would call out the FBI’s most high-profile investigation in the country as a “hoax.” No one of sound mind would forget that they had run for President at least once before, back in the year 2000.
The President of the United States has lost his grip on reality. It’s obvious for all the world to see. The only question is whether Republicans will ever do anything about it. If they don’t, the stain of their cowardice will remain on the party for a generation.
