US democracy today is in crisis because of a profound ideological and affective polarization. The chapters in this volume show that Donald Trump's grip on the Republican Party is a symptom and a catalyst, but not the cause, of the contemporary contestations of the liberal script in the US. To discern their major drivers from a longue durée perspective, each chapter takes a step back and asks three main questions: (1) How can we best describe the current contestations of the liberal script in the US, exploring the extent to which the US is unique in comparison to other liberal democracies facing similar contestations? (2) What are the main drivers and root causes that explain the current contestations and the crisis of American democracy they may precipitate? (3) What are the likely consequences for the future of American democracy?The conclusions do not lead us to expect a return to "the norm" of internal contestations of the liberal script that are common in liberal democracies and have characterized the US throughout its history. Political, economic, and cultural polarization is by now deeply entrenched in American society and is eroding "mutual toleration" as the basis of American democracy. In other words, the resilience of US liberal democracy is at stake. It is unlikely that we will see the US liberal script bounce back in the near future.This volume has emerged from research carried out as part of the Cluster of Excellence "Contestations of the Liberal Script - SCRIPTS", which analyzes the contemporary controversies about liberal ideas, institutions, and practices on the national and international level from a historical, global, and comparative perspective. It connects academic expertise in the social sciences and area studies and collaborates with research institutions in all world regions. Operating since 2019 and funded by the German Research Foundation (DFG), SCRIPTS unites eight major Berlin-based research institutions: Freie Universität Berlin, the Humboldt-Universität zu Berlin, the Berlin Social Science Center (WZB), the Hertie School, the German Institute for Economic Research (DIW), the Berlin branch of the German Institute of Global and Area Studies (GIGA), the Centre for East European and International Studies (ZOiS), and the Leibniz-Zentrum Moderner Orient (ZMO).
