Glenn Beck's viewpoint about early 20th century progressivism is greatly influenced by Ronald J. Pestritto, who holds a PhD in Government from Claremont Graduate University, and currently teaches at Hillsdale College. R. J. Pestritto has been so influential in this respect, that the GlennBeck.com web portal's page for "American Progressivism" not only uses Pestritto's teachings, but links directly to one of his books. Professor Pestritto wrote an article on the Wall Street Journal detailing "Glenn Beck, Progressives and Me". As noted on "The New York Times", when Glenn was on his Fox News show, Professor Pestritto was a regular guest.
