20% chance that he's Vince the ShamWow Guy.
80% chance that he's George Patton.
As an aside, here's why I picked those percentages: Since the 1980’s I've been reading articles that Trump has written (usually in financial magazines). That was before he got a TV show or became political. His articles were always solid, and made sense. But then again...you can never be sure about a person.
My suggestion is to allow the primary process to play itself out, with mutual respect among the remaining candidates, then get down to the horse trading and the convention — surely a solid ticket can emerge from this process and frankly, any combination is way, way better than what the other side has to offer.
So vigorous debate sure, open hostility — no, it cannot help either the eventual ticket or the nation.
