Party Ideologies in America, 1828-1996 - Paperbackby John Gerring (Author) Is American politics "ideological," or relatively consensual? Do the American parties differ from one another and, if so, how? Party Ideologies in America, 1828 1996 is a synthetic history and analysis of the ideologies of the major American parties from the early nineteenth century to the present. It is the only book currently in print that attempts such a broad treatment of the subject and that is empirically grounded.
