The entire GOP field would take up so much time, but I feel they could condense it to a quarter. This way they get the most important and juicy information, as opposed to a lot of inside information in 2012 that ultimately fell short to the inside look at '08. Each candidate would get a chapter but for the final four, and the rest of the primaries would show detailed campaign reactions.
There would be an entire quarter of the book on Trump.
And another quarter of the book would be on the Democratic Primary.
And finally the general election.
