Yes. I believe he is blind in some form.

His actual visual acuity? I expect that Donald Trump’s ability to decode text based on his ability to perceive the necessary information through visual perception is within normal range. Do we see him tripping over objects he appears not to see? No. Can he read written text? It seems he can read although Mr. Trump does not appear to like to read.

Does he have some inability to reason logically that causes him to mistake the relationship between events, people, places, and reality? It appears so, and could we call this a form of blindness. I believe we can.

Donald Trump has demonstrated the blindness to rule of law. No, we don’t use the powers of the presidency to extort foreign powers to get ahead in our own political ambitions when we withhold aide to Ukraine for dirt on political rivals.

Donald Trump has demonstrated blindness to the horrible consequences of condoning racism, “There are good people on both sides” response to Charlottesville.

Donald Trump has demonstrated blindness to clear visual facts. He insisted, in the face of photographic evidence that he had more folks attending his inauguration than Barack Obama did.

There’s many more, if I took the time.

Yeah, the dude is blind. The good news is that enough of us are seeing how this makes him unfit to be the leader of our country, and if the world still allows us to play the role, the leader of the free world.
