Lemme jump in here. Book publishing deals for these political elites are just a money laundering scheme to get each person a multi-million dollar advance (that they don't have to pay back) and then have a ghost writer do the work anyway.

The fact that he was offered one was almost certainly supposed to be hush money. The fact that he blew it up is good news. Maybe he was naive. Maybe he doesn't give a damn. We'll never know.
