As Constitution Day approaches, we feature a forthcoming book that tackles how far we’ve come in the Progressives’ quiet regime change over the last century, replacing our constitutional republic with rule by the administrative state. That book is American Leviathan: the birth of the Administrative State and Progressive Authoritarianism by Ned Ryun.

Ryun is the Founder and CEO of American Majority and Voter Gravity. The son of the former congressman, Olympian, and Presidential Medal of Freedom recipient Jim Ryun, Ned is also the author of Restoring Our Republic and The Adversaries: A Story of Boston and Bunker Hill. A frequent commentator on Fox News, Ryun currently resides in Western Loudoun County, VA, with his wife and four children.
