Radicals such as socialists, syndicalists, and anarchists are often thought of as marginal in American history. However, in the early decades of the twentieth century, progressives—those who sought to regulate big business, reduce class conflict, and ameliorate urban poverty—took the radicals' ideas very seriously.

In The New Freedom and the Radicals, Jacob Kramer deftly examines how progressivism emerged at a time of critical transformation in American life. Using original archival sources, Kramer presents a study of Wilsonian-era politics to convey an understanding of the progressives' views on radical America.

The New Freedom and the Radicals shows how the reactions of progressives to radicals accelerated the pace of reform in the United States, but how the movement was at times predisposed to repressing the radical elements to its left. In addition, Kramer asks to what extent progressives were responding to and influenced by those who opposed the state, capitalism, and the class structure altogether, as well as how progressives' views of them changed in relation to events.
