I don't think Trump will win even one primary or caucus. Which suits me just fine.
The NY Times had an interesting article on Trump's lack of organization in Iowa. After reading this I doubt he'll even show in Iowa.
Chris Wallace interviewed Trump on Fox News Sunday last week and was shown Trump's HQ. The lack of people and activity was striking. Trump attributes it to his skill as a campaigner. I'm a denier on this as well. Trump has been give a tremendous advantage by the TV networks, allowed to call in his interviews, and recognizing an industry anxious for ratings will give him non-stop airtime for all the ridiculous, insipid, contradictory statements he makes. (Bernie Sanders, Hilary, John Kasich and others have expressed their jealously recognizing they too are just as ridiculous).
I hope this bloviating distraction is out of the race by South Carolina.
