Psychological Profile

Here is a psychological profile at one time supplied by the CIA:

"His primary rules were: never allow the public to cool off; never admit a fault or wrong; never concede that there may be some good in your enemy; never leave room for alternatives; never accept blame; concentrate on one enemy at a time and blame him for everything that goes wrong; people will believe a big lie sooner than a little one; and if you repeat it frequently enough people will sooner or later believe it.: (CIA)[8]

Another remark, in regards to the same subject, in a study conducted by Henry A. Murray:

"Never to admit a fault or wrong; never to accept blame; concentrate on one enemy at a time; blame that enemy for everything that goes wrong; take advantage of every opportunity to raise a political whirlwind."

Neither of these statements were about Trump, though they could have been, if only prophetically.  They were referring to Adolph Hitler.
