I know that Donald J. Trump calls himself a “stable genius.”

Why, he even inserted the word “very” in his most recent self-glorification. His use of the v-word reminded me of something one of my mass communications professors asked me when he read one of my stories: “What does the word ‘very’ do for you?”

George Carver didn’t like the word. He thought it was unnecessary. He was right.

The president’s “stability” must be getting tested these days. He goes to Europe and has a generally hideous meeting with NATO leaders; then he ventured to London and trashed his host, Prime Minister Teresa May, only to deny he said what was published in the Sun newspaper.

It got even worse. Trump went to Helsinki and groveled at Vladimir Putin’s feet, said he didn’t know why Russia “would” interfere in our election; then he kinda/sorta took it back — the next day! — by saying he meant to say “wouldn’t.” Whatever.

The scorn is piling up. Our allies abroad cannot trust the president. He’s being played for a fool by Russia. The critics at home now include many from within his own Republican Party. Former CIA boss John Brennan and others are saying Trump’s Helsinki presser was “treasonous.”

How much can this guy take?

Oh, wait. The president has no shame. A shameless man has a deep well of whatever it is that allows him to delude himself.
