I don't think so.
Nate Silver is gay and liberal but he called all 50 states correctly in the 2012 Presidential election. If you read his views on the election prospects of various candidates you should understand that he has a lot of data at his fingertips. While I don't agree with his politics you simply cannot ignore his track record in predicting the outcome of Presidential elections.
Yes, he will miss one day and admits so, but I'm going to pay close attention to what he has to say over the next several months. The odds are he will have it figured out well before we do.
There is a thing in Hollywood called the Napoleon Dynamite Paradox.
That film was a box-office hit in 2004. It was a small independent production. No Hollywood studio ever would have made it because none of their vast reams of statistical data indicated that it ever SHOULD be made, or that it would become a hit.
This still has the people who run studios nervous and upset over a decade later, because if your data no longer allows you to consistently predict the market, you are essentially working blindfolded. To this day they still can’t figure out what all of their expensive research missed about that film.
I submit that Donald Trump is the Napoleon Dynamite Paradox of politics.
