I’m not a psychiatrist, but I don’t care. I’m going to tell you what I think about President Donald Trump’s psyche anyway. There is a more definitive book out, too, but although I bought it, I haven’t had a chance to read it yet. The book is called "The Dangerous Case of Donald Trump: 27 Psychiatrists and Mental Health Experts Assess a President." But damn my lack of credentials; I have spent 76 years on this planet, so I’m just going to tell you what I think.

I think the reason Trump is undoing or trying to undo everything that former President Barack Obama ever planned or did has nothing whatsoever to do with Trump being white and Obama being black. I think it is far less complicated than that. I think Trump, as a man, is flat-out jealous of Obama, as a man.

Think about it. Obama is better looking. In fact, I remember my grown grandson seeing a photo of Obama in Hawaii in swim trunks and pronouncing him "ripped." That is a compliment. It usually indicates six-pack abs, although I didn’t see the same photo and have no idea whether a six-pack is part of Obama’s physiology. Let’s face it, Trump is not now and possibly has never, even in playboy years, been "ripped."

These days, of course, Trump is positively blubbery. He doesn’t want his blimp-like body to be compared to the slim, fit body of our former president.

Obama is also smarter than Trump. Obama uses the English language, not just with precision, but also with grace. Trump’s use of language is rudimentary — kind of what you’d expect of someone in elementary school. And, poor Trump really tries to be clever, too. He just isn’t, and so his attempts at humor fall flat. In fact, people take his attempts as humor seriously, and it oftimes makes Trump seem cruel.

Consider his remark in Puerto Rico, the one about Hurricane Katrina being a real disaster, thereby implying that Puerto Rico’s hurricane wasn’t. That wasn’t a mean remark; it was merely inept.

Poor Trump. Let’s have a look at his more recent comment when surrounded by military leaders. He told us that the moment represented "the calm before the storm." Ominous as that would sound if uttered by a verbally proficient person, Trump’s statement has inspired curiosity rather than terror. Pundits are dismissive, one of them categorizing the remark as an example of what British politician Boris Johnson once called "The Dead Cat Strategy."

Here’s the way The Dead Cat Strategy works: No matter what is being discussed at the dinner table, were someone to toss a dead cat onto the center of the table, the conversation would change instantly and everyone would begin to discuss the unfortunate cat.

Suddenly, in light of this, a lot of Trump’s remarks make better sense. At this hypothetical Trump dinner party, in fact, we would have stacks of dead cats, piles so high that the people who are at the dinner party cannot see across the table.

So anyway, now, if you buy into my theory, you get it: Trump hates Obama because he can’t measure up to him. Obama is younger, thinner, better-looking and smarter. Come on, wouldn’t you then want all things Obama gone?
