Bruce Ackerman's recent book, The Decline and Fall of the American Republic, is a sudden shift from his previous scholarship on constitutional moments and the ability of social movements to generate minor revolutions. By acknowledging how constitutional change did not fit into his model of deliberate, deeply debated movements, Ackerman has shifted the scholarly lens to unintentional and unanticipated structural variations. Ackerman focuses his book on the political processes and events that have fostered potentially illegitimate constitutional remodeling. He acknowledges that certain features of legal scholarship have contributed to a lack of awareness of slow, structural drift, but he does not address the question in earnest, as I do in this Essay.
