The Party Decides: Presidential Nominations Before and After Reform is having quite a week—and quite an election season, in general. The book was adopted early by Nate Silver at his FiveThirtyEight blog, which led to explorations of its hypothesis here and here, and most recently here: where Silver posits the book as the most “misunderstood” of the 2016 primary season.

The point of Silver’s statement rests on whether or not a Trump nomination would destroy the Republican Party. The book’s argument is that party elites—unelected insiders—control who ultimately ends up nominated at the convention, and that decision is made many months before the primary campaign season even begins. Was anyone but Trump the nominee (say Marco Rubio, or even Jeb Bush), then The Party Decides had it right all along; if Republicans put forward DT, then it may be less a sign that the statistically supported data of the book is incorrect, and more a case of the possible dissolution of the Grand Old Party.

In the meantime, you can hear more about the book and what a Trump nomination might signify on today’s episode of The Brian Lehrer Show below:
