@glitterbag,
Trump is following another figure from history, the one who said, people will believe lies. The bigger the lie the more likely they will believe.

The source of the Big Lie technique is this passage, taken from Chapter 10 of James Murphy's translation of Mein Kampf:
But it remained for the Jews, with their unqualified capacity for falsehood, and their fighting comrades, the Marxists, to impute responsibility for the downfall precisely to the man who alone had shown a superhuman will and energy in his effort to prevent the catastrophe which he had foreseen and to save the nation from that hour of complete overthrow and shame. By placing responsibility for the loss of the world war on the shoulders of Ludendorff they took away the weapon of moral right from the only adversary dangerous enough to be likely to succeed in bringing the betrayers of the Fatherland to Justice.
All this was inspired by the principle—which is quite true within itself—that in the big lie there is always a certain force of credibility; because the broad masses of a nation are always more easily corrupted in the deeper strata of their emotional nature than consciously or voluntarily; and thus in the primitive simplicity of their minds they more readily fall victims to the big lie than the small lie, since they themselves often tell small lies in little matters but would be ashamed to resort to large-scale falsehoods. It would never come into their heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation. For the grossly impudent lie always leaves traces behind it, even after it has been nailed down, a fact which is known to all expert liars in this world and to all who conspire together in the art of lying.
— Adolf Hitler, Mein Kampf, vol. I, ch. X[1]
In that same chapter, Hitler accused "the Jews" of what he claimed was their use of the Big Lie.[1]
The principle is sometimes translated and abbreviated as the pithy saying: "Make the lie big, make it simple, keep saying it, and eventually they will believe it."
