PROGRESSIVES IN AMERICA 1900-2020 [EPUB ebook] 
Liberals with Attitude!

This is the first history of the three progressive movements in the twentieth and twentieth-first century: The original Progressives primarily in the first two decades of the twentieth century; the Popular Front progressives of the 1930s and 1940s; and recent progressives in the Democratic Party from Jesse Jackson to Bernie Sanders. Although characterized by much rhetoric, none of these movements have broken out of the reformist bounds of liberalism. The book describes the very limited outcomes of the progressive movements.
