Trump has never been coherent, not once in his life.

Remember this?

“I’m speaking with myself, number one, because I have a very good brain and I’ve said a lot of things. I know what I’m doing and I listen to a lot of people, I talk to a lot of people and at the appropriate time I’ll tell you who the people are. But my primary consultant is myself and I have a good instinct for this stuff.”

— Donald Trump, March 16, 2016, after being asked who he consults with about foreign policy

Or this?

“My uncle was a great professor and scientist and engineer, Dr. John Trump at MIT; good genes, very good genes, okay, very smart. The Wharton School of Finance, very good, very smart — you know, if you’re a conservative Republican, if I were a liberal, if, like, okay, if I ran as a liberal Democrat, they would say I’m one of the smartest people anywhere in the world — it’s true! — but when you’re a conservative Republican they try — oh, do they do a number — that’s why I always start off: Went to Wharton, was a good student, went there, went there, did this, built a fortune — you know I have to give my credentials all the time, because we’re a little disadvantaged — but you look at the nuclear deal, the thing that really bothers me — it would have been so easy, and it’s not as important as these lives are (nuclear is powerful; my uncle explained that to me many, many years ago, the power and that was 35 years ago; he would explain the power of what’s going to happen and he was right — who would have thought?), but when you look at what’s going on with the four prisoners — now it used to be three, now it’s four — but when it was three and even now, I would have said it’s all in the messenger; fellas, and it is fellas because, you know, they don’t, they haven’t figured that the women are smarter right now than the men, so, you know, it’s gonna take them about another 150 years — but the Persians are great negotiators, the Iranians are great negotiators, so, and they, they just killed, they just killed us.”
