The 80-85% of the voters that do care are going to vote for the candidate with a D or an R after their name regardless.
It's those last 15% that I think Trump thinks are shallow enough to vote for who entertains them the most. And you can say a lot of things about Trump, but you can't say he boring!
I believe that Trump believes, that in this respect that old adage that all publicity is good publicity can be applied to politics.
I don’t know about the percentages, but I can tell you as a matter of fact ...talking to people who do in fact know...that you are 100% correct on this concept.
He absolutely believes that the “entertainment vote” will go to him. He has good reason to believe that. It will.
Will it be enough? Now THAT is the question. If he is right that the “entertainment vote” is 15%....then....ain’t no way he an lose.
Your premise, however, is correct. (And incidentally, I think its explicit use in a presidential campaign is unprecedented).
