His friend Hillary in the White House. Same as any other political donation.
That doesn't compute. If he gets the R nod, he's just going to suddenly stop running and let hitlery take over? I don't think so. Doesn't match his ego. Even if he did, he would only do so if he stood something to gain. So again, what does he stand to gain that he doesn't already have? Again, the answer is NOTHING.
If he runs 3rd Party, his chances of winning are better than Nader or Perot's ever were. He has a wide appeal, and would siphon votes from both left and right, so that doesn't make sense either. Even if it did, it STILL does not answer the question, what does he stand to gain from doing it? Once again, the answer is NOTHING.
