The other books (Palin, Levin) have been on sale for months and sold 2,000+ copies per day when they were first were released.
Coulter’s new book was released on Monday and only selling less than 100 copies per day her first week an this is a major bomb. She will probably be dropped by her publisher after this performance since she won’t even get closing to paying out their advance.
I don't expect this new book to do as well as some of her earlier best sellers. It's mostly a collection of her syndicated columns with perhaps 20% new material. But it will do alright. She probably peaked with Treason in 2003, although she's written seven books since.
To think her publisher will dump her indicates lack of knowledge as to who her publisher is. She's returned to her original publisher, Regnery. They're in the business of publishing and promoting conservative writers. They've been at it a long time. They're most likely delighted to have her back. When all is said and done, her sales will easily justify their support. Keep in mind, the book's release date was only 3 days ago, October 14th.
Many have sung her Swan Song in recent years, you're not the first nor will you be the last.
Ann Coulter will laugh all the way to the bank. Ain't the free market grand!
