It was a gift from a friend, apparently. The revelation came from his ex-wife, so....I would need more than just that before I were to read more into it. There is enough reason to not vote for Trump without trying to claim he studied Mein Kampf or any Hitler book. Trump does not read, remember. His only interests are self adulation and money. He is a schemer, but he is not really a thinker.
Yes, Trump is cunning. Cunning does not preclude actual intelligence, but it is more of a conniving kind of intelligence. He knew there were millions of conservative Republicans and many non-political types who were fed up with the flood of illegal, unassimilable invaders.
So he got in front of the crowd early and rode that to victory. If not for that issue, Trump would still be looking at his image in a mirror and/or applying cheeto-based makeup to his face.
That take scheming, conniving cunning...not principled, intelligent conservatism.
