The Making of the American Conservative Mind: National Review and its Times, by Jeffrey Hart, 2005, published by the Intercollegiate Studies Institute (ISI Books)
From the jacket copy:
“National Review has been the leading conservative national magazine since it was founded in 1955, and in that capacity it has played a decisive role in shaping the conservative movement in the United States….Jeffrey Hart provides an authoritative and high-spirited history of how the magazine has come to define and defend conservatism for the past fifty years. He also gives a first-hand account of the thought and sometimes colorful personalities–including James Burnham, Willmoore Kendall, Russell Kirk, Frank Meyer, William Rusher, Priscilla Buckley, Wittaker Chambers, and, of course, the magazines founder, William F. Buckley, Jr.–who contributed to National Review’s life and wide influence.”
Not entirely biased based on the chapter titled George W. Bush: Transformative President. Though he doesn’t explain why he considered W to be transformative per se, other than disastrous Iraq war which cites W as having told a staffer in January 2001 that he planned to wage that war. He mentions the evangelicalism taking effect with prayer groups forming in the White House immediately. And to his credit, he ponders how conservative and evangelical really work, together or not.
