Trump prides himself as being inpredictable on negotiations. That’s how he wins. You can see him playing his cards very close to the vest when he skates in answering a question. Furthermore, he knows the other candidates are copying his position on some issues.
They sure are and more and more of them doing it this past week !
He not only has excellent advisers, he has a quick natural instinct for answering these questions. Maybe it has been honed by all his years as a negotiator, as well.
By the way, he mentions Carl Icahn so frequently that I wonder if he is considering him for vice president, not just a cabinet position. Seems like he is trying to get the general population familiar with the name.
