Well, that was fast. For a whole day in Washington, Thursday, May 12, Donald Trump managed to be on his best, and before this his seldom beheld, behavior, acting for once like a rational human as opposed to just being himself.

Magically, he seemed to pull off a complete transformation: He did not rage, rant, call people names, malign people’s looks, mention his genitals, demean people’s wives, accuse people’s fathers of having tried to kill Kennedy, incite people to even small forms of violence or threaten perhaps to somehow stage riots if things didn’t go as he planned.
