From prosecuting murderers in Chicago, to arguing before the Supreme Court, to authoring more than a dozen books, Georgetown University law professor Randy Barnett has played an integral role in the rise of originalism—the movement to identify, restore, and defend the original meaning of the Constitution. Thanks in part to his efforts, by 2018 a majority of sitting Supreme Court justices self-identified as "originalists." After writing seminal books on libertarianism and contract law, Barnett pivoted to constitutional law. His mission to restore "the lost Constitution" took him from the schoolhouse to the courthouse, where he argued the medical marijuana case of Gonzeles v. Raich in the Supreme Court—a case now taught to every law student. Later, he devised and spearheaded the constitutional challenge to Obamacare. All this earned him major profiles in such publications as the Washington Post, Wall Street Journal, and New York Times. Now he recounts his compelling journey from a working-class kid in Calumet City, Illinois, to "Washington Power Breaker," as the Congressional Quarterly Weekly called him. The engaging story of his rise from obscurity to one of the most influential thinkers in America is an inspiring how-to guide for anyone seeking real-world advancement of justice and liberty for all.
