Better question:
How many truckloads were bought by Democrat financiers as a payoff.
This is a tried and true Democrat money laundering scheme. Just ask Jeff Imelt.
The Obamas $63 million book deal includes bulk purchases for the filthy rich Obama (cough) Foundation to gift the Obama Presidential Center.
There’s no significant market for an Obama book.....least of all a market that buys $63 million worth of books.
