Didn't Teddy Roosevelt start it all off? I wouldn't call him a progressive. He was protecting his old memories of being a bad ass on his ranch that bellied up in the freeze.
"The Progressives were reformers in the late 19th and early 20th century who believed that in order to address modern problems, America needed to abandon the old ideas of the Founding in favor of a new expansive conception of the role of government. Progressives paved the way for modern liberalism and politics, and their core ideas are still the mainstay of today’s liberalism."
