Deeply Divided : Racial Politics and Social Movements in Postwar America

By many measures--commonsensical or statistical--the United States has not been more divided politically or economically in the last hundred years than it is now. How have we gone from the striking bipartisan cooperation and relative economic equality of the war years and post-war period to the extreme inequality and savage partisan divisions of today?

In this sweeping look at American politics from the Depression to the present, Doug McAdam and Karina Kloos argue that party politics alone is not responsible for the mess we find ourselves in. Instead, it was the ongoing interaction of social movements and parties that, over time, pushed Democrats and Republicans toward their ideological margins, undermining the post-war consensus in the process. The Civil Rights struggle and the white backlash it provoked reintroduced the centrifugal force of social movements into American politics, ushering in an especially active and sustained period of movement/party dynamism, culminating in today's tug of war between the Tea Party and Republican establishment for control of the GOP.

In Deeply Divided, McAdam and Kloos depart from established explanations of the conservative turn in the United States and trace the roots of political polarization and economic inequality back to the shifting racial geography of American politics in the 1960s. Angered by Lyndon Johnson's more aggressive embrace of civil rights reform in 1964, Southern Dixiecrats abandoned the Democrats for the first time in history, setting in motion a sustained regional realignment that would, in time, serve as the electoral foundation for a resurgent and increasingly more conservative Republican Party. This revised and updated edition features new insights into the upcoming 2016 presidential election, including data from the latest polls, as well as reflections upon the results of the 2014 midterm elections.
