You may be right, but I looked for other books for comparison, Obama for example, only came at 59%: The Audacity of Hope , same with Dreams from my father, Trump with Great Again , came at 74%. Occam razor tells me that Hillary book was brigaded by all sides and Amazon decided only to remove the negative comments.

Buy the book
Easily the best $10 you can spend (on trolling HRC)
For those interested in keeping tabs:
As of this writing Clinton is #1 in books, and Trump is #84.
All things considered, having Trump's book crack the Top 100 all from a relatively minor concentrated effort from The_Donald and /pol/ is quite impressive. They are competing in theory with a sizable national population.
The Art of the Deal (which I remember some memes said people should buy instead) is #362 as of this writing
Spez: Great Again is #16 (15:44 EDT)
