“Thelen has pitched the historical debate over insurgency-progressivism on a new level which, while it will stir much controversy, is bound to stimulate further scholarship. Historians can ignore this study only at their own peril. Future writings on Progressivism, whether or not they agree with Thelen's work, must come to grips with it. Higher praise can hardly be accorded a work by any scholar.”—Reviews in American History
“A splendid little book, jumping with ideas and insights. . . . David Thelen has shrewdly and provocatively sketched out a major thesis concerning the rise and fall of progressivism.”
—Wisconsin Magazine of History
“More than a biography of La Follette, this study is a thoughtful documentary of the insurgent movement he led.”—The Christian Science Monitor
