This article analyzes the hierarchy of factors in the development of crisis trends in a consolidated democracy using the example of the United States of America. The authors assess the surge of political instability in the United States, which led to the deconsolidation of the liberal democracy regime, through the prism of centrifugal processes within the American elite and the erosion of democratic institutions over the past 30 years. The main problem of the study is the contradiction between the crisis of democratic regimes in the countries of the Euro-Atlantic region and the high indicators of the factors of the consolidation of democracy, according to classical political science theories. The authors use the path analysis method to determine the main path and hierarchy of factors of erosion of the liberal democracy regime in the United States, which is an example of the "old" democracy and, according to traditional political science, is the most protected from destructive processes. Consideration of the case of deconsolidation of the liberal democracy regime in the United States, thus, sheds light on the possible ways of democracy reversion and risk factors for stability of democratic political systems
