Big Mike got a book deal yet he hasn't sold too many copies. Why would a publisher keep signing up these leftists when they know darn good and well they will never recoup the millions in advance fees?

Over 725,000 units in the U.S. and Canada on its first day of publication (November 13, 2018) More than 2 million units in the U.S. and Canada during its first 15 days of publication (November 13-27, 2018) Over 10 million copies worldwide as of March 2019

Now these numbers are the number of books sold to book stores, not how many made it out the doors. The book stores are always left holding the bag.
