The GOP presidential candidate’s new biography was omitted from the liberal paper’s published list, despite the fact that the book had sold more copies in its first week than all but two of the Times’ bestselling titles.

Ted Cruz has asked other campaigns to “consider joining with us” to convince Fox News to change the way it uses national polls to determine which candidates are invited to participate in the network’s first presidential debate August 6. “That process involves a careful analysis of data, and is not influenced in any way by the content of a book, or by pressure from publishers or book sellers”, Murphy said.

Cruz acknowledged public attention had helped propel his book onto the list.

“A Time For Truth ranked high on the other publishing industry bestseller lists including Nielsen Bookscan (#4), a subscription service that tracks the vast majority of book sales in America, The Wall Street Journal (#4) and Barnes and Noble (#7)”, HarperCollins spokeswoman Tina Andreadis told BuzzFeed.

Cruz said he’s glad the book is being listed but added, “It seems to me there are a lot of conservative authors the New York Times discriminates against”. (Books from conservative pundits such as Bill O’Reilly, Glenn Beck and Ann Coulter have appeared on Times’ list.).

In a memo sent to fellow GOP campaigns on Wednesday, Chris Wilson, who serves as director of research and analytics for the Cruz campaign, called Fox News’ standards for deciding which national polls are used in its debate entry process “unclear”.

The New York Times declined to offer evidence of the alleged bulk purchases or have given Senator Cruz an apology.

However, both HarperCollins, the publisher of Cruz’s book, and Amazon insisted that there was no evidence of such bulk purchasing.

Essentially, that’s when a publisher or organization buys up copies of the book in strategic locations in an attempt to artificially inflate sales numbers.

Senator Cruz’s memoir had been selling briskly, but the newspaper refused to add it to their list, claiming that numerous purchases were so-called ‘bulk purchases.’. “If they want to be credible journalists, the public editor needs to investigate their methodology, see if they’re discriminating against authors that they may have different political views [from]”, Cruz said.
