I suspect that internal polling has Trump in a position to spend some political capital. In other words — to late to stop his nomination.
Now he is free to do the ‘spooky things’ well before the primary is even over — if my suspicions are correct. By looking spooky to us, he can corral the Establishment and remould it.
If my suspicions are wrong, self-sabotage? I doubt that.
