(CNN) Former New Jersey Gov. Chris Christie saw the Trump campaign up close and personally. After endorsing Donald Trump's presidential campaign in February 2016, Christie was by the candidate's side for much of the campaign and ran the transition effort once Trump won -- until he was fired from that gig.

Christie's history with the campaign means that when he talks about Trump and those around him -- as he does in his new book "Let Me Finish" -- we should all listen. And in an interview with The New York Times' Maggie Haberman about the book -- and his time with Trump -- Christie offers up a theory on why he doesn't believe there was any collusion with the Russians. Here it is:

"Mr. Christie said the campaign was too disorganized and threadbare 'to run a Tom Clancy operation,' and said he never saw evidence of collusion with Russian officials."

What Christie is arguing here is that the candidate and the campaign he ran was simply not sophisticated enough to possibly run some sort of broad-scale collusion operation with the Russians. That they were too dumb, politically speaking, to pull off anything close to this.

Which, is a) intriguing b) insulting to the Trump campaign and c) something I have heard from people who were tangentially connected to Trump's campaign in 2016.
