Every four years, the drama of presidential selection inspires a reassessment of our political parties. Central to this assessment are the delegates who gather at Democratic and Republican national conventions. Parties in Transition presents a richly modulated body of data of the changing attitudes and behaviors of these delegates—their ideologies and loyalties, their recruitment into presidential politics, their persistence in or disengagement from it. Covering three recent sets of conventions and involving over five thousand delegates, this comprehensive study makes an essential contribution to our understanding of American party politics. "Richer and more authoritative than most of the best works in the field." —Election Politics "A most important study of change in the American political scene....Richly deserves to be read." —John H. Kessel, Ohio State University "[A] shrewd and sophisticated analysis....Both scholars and practitioners should read this book and ponder it." —Austin Ranney, University of California, Berkeley
