I think Trump is more normal than he behaves. He just wants to get votes. But the primary is over, so maybe he forgot it is time to stop catering to crazy Republicans and start catering to normal people. But it is too late, I think, or he is not so smart as he claims. The Interwebs record all things. Also, he is clearly into himself way too much to be a leader. Good leaders serve the people they lead. The cult of Trump would not work in this day and age.
It would have been interesting had Trump just tried to be normal and not so full of himself, and said sane things. Yet I suppose the nutty GOP base would not have voted for him.
Yet seriously, Republicans are often crazy by default, so I suppose Trump was being normal, for them, more or less.
