He said he could beat Secretary of State Rex Tillerson in an IQ test. Trump then insisted he never undercuts anyone and has confidence in the man who allegedly called him a “moron.” This sounds, colloquially speaking, nuts. Who behaves this way?

His tweet insulting Sen. Bob Corker (R-Tenn.) was weak and incoherent. “The Failing @nytimes set Liddle’ Bob Corker up by recording his conversation,” Trump wrote without explaining the origin of “Liddle.” He insisted that Corker was “made to sound a fool, and that’s what I am dealing with!” Actually Corker has be lauded for his remarks, which both he and the Times recorded.

Trump said he won’t fill a lot of jobs because there are hundreds of thousands of people in government. He apparently is unaware that assistant secretaries, undersecretaries and other political appointees are needed to carry out a president’s agenda. Maybe he can’t find anyone to work for him and has given up. Maybe his aides can’t get him to pay attention. He’s not running the executive branch; it’s too much for him even to fill senior spots.

He brushed aside the notion he was setting the country up for World War III by insisting we were on the wrong track but we’re not anymore. Does anybody think he could identify with any precision what our policies toward North Korea and Iran might actually be? He doesn’t seem able to explain how not talking to North Korea because it is a “waste of time” has put us on the road to a peaceful resolution.
