Oh I know that Theodore Roosevelt established the Progressive Party. He also staked his reputation on breaking up large corporations, recognizing their pernicious influence on society. I wonder what the reaction would be today if he tried to do so, what with so many of our elected government officials being bought and paid for.

I haven't read Goldberg's book, but there is nothing progressive about fascism. In fact, fascism is just about the opposite of progressivism. Nazism was not the only form of fascism, but was the most prominent.
