What I can’t figure is whether he’s trying to pre-delegitimize a Clinton victory, excuse his own failings as someone else’s fault, or incite violent voter suppression by his supporters.

I’ve long suspected he doesn’t really want to BE President, and maybe if he can’t win, he doesn’t even want to RUN FOR President anymore. After a couple failed attempts to pivot, perhaps even he realizes he can’t. He’s as much as said that if he can’t win being himself, so be it.
