While your (and your dad’s) thesis is an interesting one, it ignores two salient facts. First, he said long ago that he wanted to run for president. Second, that he had a presidential bid in 1999 with a third part (sorry, but I don’t remember the name of the party…read a recent article in Newsweek about his Cuba mis-steps and it was reported in that article).
I agree with you that it’s all about more-and-more media attention for his brand. As I’ve said before, he worships at the altar of money. That’s all he really cares about (and himself, of course).
