I am trying to fathom the reasons that millions of American voters are continuing to argue for the re-election of the man pictured here.

So help me I am at a total loss.

Donald Trump keeps threatening to do bodily harm to our democratic process if the November presidential election doesn’t turn out the way he wants.

He is indicating he might not accept the result of an election that favors Joseph R. Biden Jr. He already has said that a Biden victory would guarantee a “rigged” election. So he’ll do what? Demand a recount? Toss the ballots out? Start over?

Then he said he deserves a “do-over” because President Obama and Vice President Biden “spied” on his campaign during the 2016 election season. Spied? Oh, that was when the FBI and others reported to the Obama administration that Russians were interfering in the election, so the Obama folks wanted to take a closer look at it.

The FBI already has determined there was no “spying.” That hasn’t shut Trump’s pie hole.

The latest gem is that he might seek a third term if — and I am swallowing hard to say these next few words — he wins re-election.

Oh, but wait. The U.S. Constitution’s 22nd Amendment says a president can be elected twice. That’s it. No more. Is he going to demand an amendment to the Constitution? Good luck with that one, Donald.

Watching The Donald flail and flounder this way simply brings to mind my astonishment in the support he continues to pull from the roughly 40 percent (give or take) of the American voting public. What on Earth, in the name of political sanity, do they see in this individual?

The third term suggestion might be some sort of Trumpian joke, although The Donald seems to possess no discernible sense of humor. The “spying” allegation is just one more smear that Trump insists on leveling at Barack Obama, given what I believe is his intense envy at the sophistication his immediate predecessor demonstrated during his two terms in office.

Whether to accept the election result if former VP Biden wins? In some sort of macabre way, many of us saw that one coming long ago … about the time he rode down that Trump Tower escalator to declare his candidacy for the only public office he ever sought.

Trump is unhinged.
