Nicholas Jacobs (Colby College) and Sidney Milkis (University of Virginia) have a new book, Subverting the Republic: Donald J. Trump and the Perils of Presidentialism (UP of Kansas, 2025), focusing on the idea of presidentialism, which is a way to think of political systems that include a dominant president or executive. In the United States, with the original constitutional system of separate co-equal branches of government, presidentialism disrupts the structure that was initially constructed under the U.S. Constitution. Over the course of more than two centuries, the United States has contended with the waxing and waning of presidential power within the multi-branch system. But Jacobs and Milkis maintain that since the 1990s we have seen an expansion of presidentialism, with a collective tendency to invest greater responsibilities and power in the presidential office itself as well as in the person who is serving in that capacity. Part of this thesis is also about how different, competing forces and ideologies have pushed for the use of presidential power to solve cultural struggles, which are not necessarily the institutional or structural role of the presidency. While the growth of American presidentialism may be more contemporary, it has origins in the struggles and ruptures of the 1960s and the 1970s—which were never fully resolved, especially in regard to who belongs within the American community. Subverting The Republic spends time examining this historical framework to help us think about the current structural, political, and cultural contexts, and especially the place of President Donald J. Trump within our understanding of presidentialism.

This book is a careful and deeply researched historical and political analysis of the shifts and changes in how the American presidency has operated over the past 75 years, and grounds many of the actions we have seen within both Trump Administrations, as well as much of the pushback against some of these actions and assertions of power. In weaving together the historical background with the structural form of the presidency and the various tools that a president has at his command, Jacobs and Milkis lay out both the precedents relied upon by presidents of the 21st century, especially Donald Trump, but also the anomalies of the Trump Administration and actions. While Subverting the Republic: Donald J. Trump and the Perils of Presidentialism went to press before President Trump was re-elected in 2024 (and there is a brief postscript that is included, noting the results and considering what the second Trump Administration might look like), the authors noted in our conversation that much of what they discuss about the first Trump Administration in the book has only grown and expanded in the second Trump Administration. This is an important analysis of the office of the American presidency and how that office, as conceived of by the Founders and situated within a constitutional system that includes other centers of power and responsibility, has evolved rather dramatically from that initial form and structure.
