Interesting theory. As a Cruzer, I could come up with an analogous theory with Trump siphoning off the Conservative vote to knock Cruz off.
The difference is that Donald Trump is not owned by anyone. He made his money in real estate, not finance and stocks. The Bush-Clinton establishment has absolutely no hold over him, and he has the reputation of being absolutely ruthless with people who cross him.
Donald Trump really is a person after the type of Samson: Doesn’t drink, wild hair, chases women, will kill you or your friends if you treat him unfairly, and finally brought down the Temple of Dagon on the Philistines. (Judges 13-16)
