AbstractRegarding the implications of the political developments of the last five years for the study of American political development (APD), this article argues that the unprecedented Trump phenomenon and its problematic repercussions for U.S. democracy have greatly enhanced the value of a comparative perspective, which can draw instructive lessons from the fate of attacks on liberal democracy by populist leaders in other countries. Comparativists examining the contemporary United States initially highlighted the risks of populist leadership (i.e., political agency), stressed the possibilities of democratic backsliding, and examined how popularly elected chief executives can undermine democracy from the inside—all of which fueled grave concerns. Yet for a more realistic assessment of populism's actual danger for U.S. democracy, one must analyze the probability of such a deleterious outcome. Therefore, researchers need to embed agency in contextual conditions and investigate what institutional, structural, cultural, and conjunctural factors empowered populist leaders to destroy democracy in some countries, whereas other constellations of these factors have impeded democratic backsliding in many other nations. With this move beyond a primary focus on agency, comparative analyses align with APD's longstanding attention to complex context factors. Interestingly, such a comparative perspective corroborates the distinctive institutional strengths and relative resilience of U.S. democracy.
