In 2001, historian Rick Perlstein published 

, which examined the conservative ascendancy through the lens of Barry Goldwater’s 1964 White House run. Now comes the sequel, 

, in which he explains how Richard Nixon emerged in the Goldwater aftermath as the unscrupulous tribune of a “silent majority” infuriated by the social instability gripping ­America.

is, at times, an eloquent narrative of a society in chaos. Perlstein argues that Nixon capitalized on that ­unrest—­crime, rioting, pornography, “women’s liberation”—to win the presidency. Appropriating the tactics and strategies of conservative leaders such as California governor Ronald Reagan and Alabama’s George Wallace, Nixon used racial codes, patriotic symbols, and get-tough language to appeal to suburbanites who sought the restoration of order to their streets and college ­campuses.

Nixon’s appeal to the “silent majority” and his ­us-­versus-­them brand of politics is by now a relatively familiar story. Yet, with an anthropological eye for detail, Perlstein mines news articles, numerous historical monographs and books of the period, and, to a lesser degree, archival documents to capture vividly the rage that animated this era’s politics among both conservatives and the New ­Left.

Hardhats clubbed antiwar demonstrators in New York City, and Nixon’s vice president, Spiro Agnew, emerged as a ­“law-­and-­order vanguardist” who railed against campus ruffians and attacked the liberal media as “nat­tering nabobs of negativ­ism.” The National Guard, rifles and bayonets at the ready, cracked down on protesters at the 1968 Democratic Convention in Chicago while chants of “kill the pigs!” went up as police waded into the ­crowds.

But there is a cartoonish and ultimately unconvincing quality to Perlstein’s portrayal of political figures. Nixon is purely Machiavellian. Agnew is irredeemably vicious. George McGovern is utterly incompetent. Politicians of all stripes are depicted as lacking substantive ideas about public policy and foreign affairs. The Left and the Right are united only by their incivility and contempt for the other side. Hu­man decency is virtually absent from these ­pages.

There are other problems as well. The narrative tends toward the grandiose, as if an already dramatic storyline had to be written with big and bold strokes to capture the tenor of the times. Perlstein italicizes (“Agnew 

 beards”). When Nixon aide John Erlichman warned administration official Leon Panetta to stop saying that Nixon favored civil rights, Perlstein needlessly deadpans, “Silly Leon.” Nixon is described as “lustily” pursuing his ­goals.

Still, Perlstein’s history of violence in ­Amer­ica—­of street crime but also ideologically charged at­tacks on Americans by other Americans, and their effect on electoral ­politics—­is a stark re­minder of the bitter divisions of the Lyndon Johnson–Nixon years. Despite its overreach, 

 is an im­por­tant work of synthesis, capturing a moment when ideological, racial, gender, and moral conflicts rent the electorate. While issues including class tensions, the growing influence of the Sunbelt in presidential politics, and Nixon’s foreign policy receive short shrift, Perlstein provides a thorough and provocative analysis that reinforces, with a wealth of detail, the roots of conservatism’s successes.

Whether American politics is still defined by the violence of Nixon’s age, as Perlstein concludes, is debatable. Nonetheless, public morality did emerge as a dominant factor in American politics in the late 1960s. The Watergate scandal ultimately derailed Nixon’s career. But his Republican successors moved in to pick up the pieces, and

 is a bracing reminder of how some divisions from Nixon’s presidency continue to haunt debates about abortion rights, flag pins, and gay ­marriage—­issues likely to play a part in presidential politics for the foreseeable ­future.
