The U.S. Senate is so sharply polarized along partisan and ideological lines today that it’s easy to believe it was always this way. But in the turbulent 1960s, even as battles over civil rights and the war in Vietnam dominated American politics, bipartisanship often prevailed. One key reason: two remarkable leaders who remain giants of the Senate—Republican leader Everett Dirksen of Illinois and Democratic leader Mike Mansfield of Montana, the longest-serving majority leader in Senate history, so revered for his integrity, fairness, and modesty that the late Washington Post reporter David Broder called him “the greatest American I ever met.” The political and personal relationship of these party leaders, extraordinary by today’s standards, is the lens through which Marc C. Johnson examines the Senate in that tumultuous time. Working together, with the Democrat often ceding public leadership to his Republican counterpart, Mansfield and Dirksen passed landmark civil rights and voting rights legislation, created Medicare, and helped bring about a foundational nuclear arms limitation treaty. The two leaders could not have been more different in personality and style: Mansfield, a laconic, soft-spoken, almost shy college history professor, and Dirksen, an aspiring actor known for his flamboyance and sense of humor, dubbed the “Wizard of Ooze” by reporters. Drawing on extensive Senate archives, Johnson explores the congressional careers of these iconic leaders, their intimate relationships with Presidents John F. Kennedy and Lyndon B. Johnson, and their own close professional friendship based on respect, candor, and mutual affection. A study of politics but also an analysis of different approaches to leadership, this is a portrait of a U.S. Senate that no longer exists—one in which two leaders, while exercising partisan political responsibilities, could still come together to pass groundbreaking legislation—and a reminder of what is possible.

While political history has plenty to say about the impact of Ronald Reagan's election to the presidency in 1980, four Senate races that same year have garnered far less attention - despite their similarly profound political effect. Tuesday Night Massacre looks at those races. In examining the defeat in 1980 of Idaho's Frank Church, South Dakota's George McGovern, John Culver of Iowa, and Birch Bayh of Indiana, Marc C. Johnson tells the story of the beginnings of the divisive partisanship that has become a constant feature of American politics. The turnover of these seats not only allowed Republicans to gain control of the Senate for the first time since 1954 but also fundamentally altered the conduct of American politics. The incumbents were politicians of national reputation who often worked with members of the other party to accomplish significant legislative objectives - but they were, Johnson suggests, unprepared and ill-equipped to counter nakedly negative emotional appeals to the 'politically passive voter.' Such was the campaign of the National Conservative Political Action Committee (NCPAC), the organization founded by several young conservative political activists who targeted these four senators for defeat. Johnson describes how such groups, amassing a great amount of money, could make outrageous and devastating claims about incumbents - 'baby killers' who were 'soft on communism,' for example - on behalf of a candidate who remained above the fray. Among the key players in this sordid drama are NCPAC chairman Terry Dolan; Washington lobbyist Charles Black, a top GOP advisor to several presidential campaigns and one-time business partner of Paul Manafort; and Roger Stone, self-described 'dirty trickster' for Richard Nixon and confidant of Donald Trump. Connecting the dots between the Goldwater era of the 1960s and the ascent of Trump, Tuesday Night Massacre charts the radicalization of the Republican Party and the rise of the independent expenditure campaign, with its divisive, negative techniques, a change that has deeply - and perhaps permanently - warped the culture of bipartisanship that once prevailed in American politics.
