“People will be watching most closely to see how McCabe’s does in comparison to James Comey’s,” said one industry executive. McCabe has a big hill to climb. Former FBI director Comey’s “A Higher Loyalty: Truth, Lies, and Leadership” reached No. 1 and sold 238,000 hardcover copies for the Flatiron imprint of Macmillan since its July release, according to NPD BookScan.

The reigning No. 1 anti-Trump blockbuster is still Michael Wolff’s “Fire and Fury: Inside the Trump White House,” which sold 1.02 million copies in hardcover following its January 2018 release by Macmillan’s Henry Holt imprint. Now in paperback, the publisher said it has sold over 4 million copies worldwide when e-books and audiobooks and foreign sales are counted.

Just a whisper behind him is investigative reporter Bob Woodward’s “Fear: Trump in the White House,” which was released by Simon & Schuster only in September but has already sold 982,000 hard cover copies.
