Writing for JOTWELL's Legal History Section, 
Kunal Parker (University of Miami School of Law) has posted an admiring 
review of 
Tocqueville's Nightmare, by my co-blogger 
Daniel R. Ernst (Georgetown University Law Center). Here's the first paragraph:
Daniel Ernst’s book, Tocqueville’s Nightmare: The Administrative State in America,
 is a significant addition to the growing literature on the history of 
the administrative state. However, it also compels a rethinking of the 
received historiography of twentieth century American legal thought. It 
is to the latter contribution that I will devote this brief review.
Here's a bit more:
We often tell the history of American legal thought in the first half
 of the twentieth century as a history of the retreat of “law” before 
the advance of democratic “politics.” The New Deal, accompanied by the 
U.S. Supreme Court’s decision to rethink its position in Lochner,
 represents the triumph of democratic “politics,” the displacement of 
law generated by a common lawyerly judiciary by law generated by 
legislatures and the administrative agencies they created. 
Ernst’s book complicates this story considerably. If one follows the 
implications of his account, the story of the contest between “law” and 
democratic “politics” in the first half of the twentieth century is not 
any simple story of the retreat of “law” before the forces of 
democratic “politics.” It is instead a story of how “law,” by giving up 
its ability to check democratic “politics” on substantive grounds, 
instead suffused democratic “politics”—one important locus of which was 
the new administrative state—by becoming procedure. Through his
 study of politics of the early twentieth century administrative state, 
Ernst thus gives us rich substantive account of one important site of 
the changing career of “law” in relationship to democratic “politics,” 
of its emerging ontology as procedure.
