I haven't read the book, and I certainly won't enrich Dean by purchasing it, even at BJ's price. Vivian Paige is fond of it; Shaun Kenney rightly calls it "silly."
Dean is just the latest in a ... well, rather short line of "conservatives" who have attempted to capitalize on demonizing the GOP and its dominant ideology from an "insider's" view.
But let's remember, after all, that John Dean probably was never really a "Conservative." After all, he was part of the Nixon Administration, an administration "Conservative" only in comparison to the naked socialism advanced by its predecessor and in comparison to Hubert H. Humphrey and George "No Enemies to the Left" McGovern. And let's remember, too, that the guy was part of the corruption of the Nixon Administration. Here's what Wikipedia has to say about his role:
Dean pled guilty to obstruction of justice before Watergate trial judge John Sirica on October 19, 1973. He admitted supervising payments of "hush money" to the Watergate burglars, notably E. Howard Hunt, and revealed the existence of Nixon's enemies list. On August 2, 1974, Sirica handed down a sentence of one to four years in a minimum-security prison. However, when Dean surrendered himself as scheduled on September 3, he was diverted to the custody of U.S. Marshals and kept instead at Fort Holabird (near Baltimore, Maryland) in a special "safe house" holding facility primarily used for witnesses against the Mafia. He spent his days in the offices of the Watergate Special Prosecutor and testifying in the trial of Watergate conspirators Mitchell, Haldeman, Ehrlichman, Robert Mardian, and Kenneth Parkinson, which concluded on January 1, 1975. Dean's lawyer moved to have his sentence reduced, and on January 8, Sirica granted the motion, adjusting Dean's sentence to time served.If he weren't trashing true "Conservatives," would MSM types like Keith Olbermann be giving him the time of day? Doubtful.
Dean is and seems to have always been, at his heart, little more than a sleazy opportunist. He is certainly a turncoat if, indeed, he ever was really a Conservative.
