Anyone who has been paying attention to Donald Trump’s campaign is well aware that he is functionally illiterate. His speeches are nothing more than bragging about how awesome he thinks he is, and hurling childish insults at his opponents and critics. He has been rated as speaking at a third grade level (which may still be over the heads of his followers). And he repeats himself incessantly as if he has forgotten what he just said moments ago.

But there may be an even bigger problem than his inability to engage in an adult dialog. He may be suffering from terminal boredom. It appears that a surprisingly large number of people and things just bore The Donald silly. Of course, it may just be that his comprehension skills have declined severely in his golden (gaudy) years and he is unable to stay awake. After all, a couple of months ago he was complaining bitterly about the burden of a proposed three-hour debate, and recent reports show that his stamina on the campaign trail is alarmingly low. Ironically, he accuses his rivals of being “low-energy” or lacking “strength and stamina,” when they are demonstrably more active than he is.

These are issues that Trump should address with his doctor. They may be indications of more serious health problems. But regardless, there is abundant evidence that he is not capable of performing the duties of the President of the United States, either physically or psychologically. Here is a sampling of some of things that bore Donald Trump, beginning with his predictable disappointment with President Obama’s State of the Union speech last night:

• The #SOTU speech is really boring, slow, lethargic – very hard to watch!
• John Oliver had his people call to ask me to be on his very boring and low rated show.
• #DemDebate was really boring but had a lot of fun live tweeting and picked up by far the most followers.
• David Letterman’s Show Has Become ‘Boring And Mundane’.
• The Oscar broadcast is really boring – where is the glamour and beauty?
• One of the worst and most boring political pundits on television is @krauthammer. A totally overrated clown who speaks without knowing facts
• Just tried watching Modern Family – written by a moron, really boring,
• Adam Moss, editor in chief of @NYMag is quickly losing his reputation in that @NYMag has become so boring and so irrelevant.
• The @nfl games are so boring now that actually, I’m glad I didn’t get the Bills.
• The failing @nytimes should focus on fair and balanced reporting rather than constant hit jobs on me. Yesterday 3 boring articles, today2!
• .@CNN has to do better reporting if it wants to keep up with the crowd.So totally one-sided and biased against me that it is becoming boring
• Why don’t U [Bill O’Reilly] have some knowledgeable talking heads on your show for a change instead of the same old Trump haters? Boring.
• Just cancelled my subscription to @USATODAY, Boring newspaper with no mojo — must be losing a fortune. Founder has always been a lightweight — just like his paper
• I skipped a speech given years ago at Mar-a-Lago by dopey @GeorgeWill because he’s BORING—he never forgot!
• Dopey Arianna @huffingtonpost is really after me–boring story after boring story…but I hear she is in big trouble!
• Just finished reading a poorly written & very boring book on the General Motors Building by Vicky Ward. Waste of time!
• I don’t know @SamuelLJackson, to best of my knowledge haven’t played golf w/him & think he does too many TV commercials—boring. Not a fan.

Obviously Donald Trump has a problem maintaining a normal level of interest. And it goes beyond just politics to include the media, sports, and entertainment. Imagine if a defective mind like that were responsible for national security. He may just find Yemen or Ukraine too boring to bother with. And it’s fairly certain that boredom would set in over matters related to big banks, civil rights, Climate Change, and campaign financing.

In some respects I know how Trump feels. I’m pretty bored with his racist, hateful, totalitarian, egomaniacal ravings. And apparently I’m not alone. A “supporter” at one of his rallies this week was ejected for shouting out “This is boring. Tell some jokes.” That’s a perfectly appropriate criticism for a candidate that only exists because of his celebrity and alleged entertainment value.
