American politics is the study of the political processes, institutions, actors, and behavior within the United States. This research area encompasses the study of political parties, elections, public opinion, government institutions (such as Congress, the presidency, and the judiciary), and public policy. Scholars in this field also examine the role of interest groups, media, and social movements in shaping political outcomes. Research in American politics often seeks to understand how power is distributed and exercised in the American political system, as well as the impact of political decisions on individuals and society as a whole.
