Trump is a bigot
No
and a blowhard
Yes
with no chance of winning the nomination.
Probably So.
I agree that he is unlikely to gain the Nomination or even less likely win the Presidency.
But look at the notice he and his "brand" are getting right now.
This could be enough to satisfy , and he is getting it already.
Watch him sell a book now, or give televised advice , or in a dozen other ways harvest this .
As a second possibility , he could show up at a contested convention with enough delegates to wheel and deal with them, this would not have to be a really great number, just enough to fill the hole in someone else's ranks.
Thirdly , it isn't impossible that he could be chosen, and he could be running against Hillary Clinton , the Democrat with whom he has the most in common.
