Richard Nixon looms over the twenty-first century. There is Nixon as a cultural kitsch object, with his gestures and his catchphrases and deeply unsettling television appearances and his damp paranoiac scowl that makes for an easy punchline. There is Nixon now, in 2019, invoked as government hearings and special prosecutor's reports swirl around us-- former White House counsel and Watergate witness John Dean recently testified, and former Nixon ratfucker Roger Stone flaunted his Nixon tattoo and victory pose after his arrest. But Nixon casts a larger shadow in politics. In Nixonland, Rick Perlstein uses Nixon as a stand-in for American polarization along new axes, divisions based on apocalyptic language and violence.
