Just another sign of his self-centredness and narcissism that he views a loss purely in terms of his own 'waste of time' rather than anything about the wider group he's brought along with him. I mean usually in a situation like that you're supposed to offer your followers some hope, thank them, show your appreciation for them, but...nope...for Trump, he can't see past his own personal loss.
I imagine if he does actually lose that someone will shove a concession speech in front of him and basically force him to hit all these other notes that he wouldn't naturally incline towards himself.
While I'm sure his camp have been preparing for all outcomes, I wonder if he's had any hand in preparation for both eventualities or if a concession scenario would be completely seat-of-his-pants stuff for him personally. From the article in the OP I wonder if anyone's had the balls to put anything like a concession speech in front of him for review 'just in case', or if he's just too fragile for it, and would be left completely unprepared if it does happen.
