Donald Trump’s delusion is well-chronicled.

He keeps touting all the “success” he has enjoyed since becoming president of the United States. Trump keeps lying about having passed more legislation than any president in history.

If matters were going as swimmingly as Trump keeps insisting, then I am forced to ask this fundamental question:

Why do polls keep showing a tangible, real distrust among Americans?

The RealClearPolitics average of polls now stands at 39.3 percent approval of the president; 56.2 percent of Americans polled disapprove of the way he is doing his job.

I mention the RCP poll average because of its reliability. It factors in all leading public opinion surveys and averages them out. As near as I can tell, 39.3 percent approval stinks.

If I were in Donald Trump’s shoes, I’d be mighty concerned about it. I also would exhibit a ton of reticence in talking about the phony success rates.

This guy doesn’t get any of it. He doesn’t know most Americans feel about him. Sure, he has his base. The diehard Trumpkins around the country are standing by their man. The president is feeding off of that and conflating their support for his policies with the national mood — which reality should tell him doesn’t reflect the infatuation of those among his political base.

Indeed, the president is delusional.
