Hillary Clinton is big on using books to push her narrative. The problem with that is no body but those who worship her read those books because everybody else knows they are nothing but BS, like her. She is up to her neck with Fusion GPS criminality so it stands to reason she is likely behind having them publish this BS book as well.
People don’t have to read these books because the media dutifully report on it multiple times a day and get other media types to comment on the reporting. Just go back a few weeks to the release of the book about the Kavanaugh hearing and how the media ran with the BS in it.
