MixedNew York Journal of BooksInitially, Kalb writes like a mystery author, tracking down where he believes Trump, who is not known for reading history books, learned of the enemy phrase. He presents a strong argument that Trump heard the phrase from a speech made by a Democratic pollster, Pat Caddell, who repeated the phrase in an interview on Breitbart radio ... Kalb’s argument is compelling ... But when Kalb pulls the authorial lens away from Trump, the book lags ... Kalb writes at length about the McCarthy communist hearings and of Edward R. Murrow’s challenge to McCarthy. The narration feels stale ... Kalb flings his final assault, calling Trump the true enemy of the people. It’s an easy barb and one that feels beneath the book’s intellectual discourse.
