"If recent elections have proven anything, it is how deeply polarized American voters really are. In this remarkably perceptive and probing book, Campbell explains how and why this phenomenon began and developed. You'll be surprised by some of his findings. We can't reduce paralyzing polarization until we truly understand it. Thanks to Campbell, we're much better equipped."—Larry J. Sabato, author of The Kennedy Half-Century"Regardless of where you stand in the debate about polarization, there is no question that anyone interested in the subject must seriously engage Campbell's nuanced theoretical arguments and careful empirical analyses."—Morris P. Fiorina, Stanford University"Rigorous, balanced, and insightful, Polarized is a major contribution to our understanding of political polarization."—George C. Edwards III, author of Predicting the Presidency: The Potential of Persuasive Leadership"Campbell makes a forceful case for his point of view, arguing that America is no longer a pluralist polity characterized by a moderate, compromising politics. Even if one disagrees with him, one knows where he stands and why. Polarized is a learning experience, for protagonists and antagonists alike."—Michael S. Lewis-Beck, coauthor of The American Voter Revisited"A must-read for anyone interested in the evolution and current state of American politics. Campbell flips much of the conventional wisdom about polarization on its head—rather than being a top-down or elite-driven phenomenon, polarization is driven largely by the American public and their shifting views."—James N. Druckman, coauthor of Who Governs?: Presidents, Public Opinion, and Manipulation
