The tragedy in Arizona reveals America's long, sad history of political hate and paranoia says historian Dominic Sandbrook—and its not going to disappear any time soon.
Dominic Sandbrook taught American history at the University of Sheffield and is a former senior fellow at the Rothermere American Institute, Oxford. He is the author of Eugene McCarthy: The Rise and Fall of Postwar American Liberalism, and the forthcoming, Mad As Hell: The Crisis of the 1970s and the Rise of Populist Right.
