Don't get me wrong....I don't dispute that his tweet was racist. It was, absolutely. However, I think there was a secondary and hidden motive which Trump doesn't have the wit to devise on his own.
And, my suspicion continues based on the grammatical content. When a guy who is borderline illiterate correctly avoids ending a sentence with a preposition, I smell a rat.
