“Primary rules”

From the latest installement of Heather Cox Richardson’s Letters from an American, someone’s “primary rules”:

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.

Sounds like Donald Trump, but it’s not. Can you guess who?
