I recognized some sales techniques that Trump was using early on from a sales course I took years ago. Things like not finishing sentences. It allows the buyer to end the sentence any way they want it to end so they sell the product or service to themselves without the seller being tied to a promise or guarantee.
Another is constantly shifting subjects to keep the buyer off balance so the buyer must rely on the seller to keep track of the conversation. Trump did this in the interview about federal lands when he shifted from why the feds must control the land to Hillary will take your guns away. One doesn't have anything to do with te other. (In reality, more federal land eases gun control)
I have never been part of #neverTrump, and, that being said, you are dead on about Trump and his hard sell tactics - anybody who has ever worked in the business can recognize them on sight, and you only mentioned a few of his tactics.
Did what he set out to, he won, successfully sold his brand last night. So he can win elections, knew that, let's see if he can govern worth a damn.
