American Politics involves studying politics in the United States at the federal, state, and local levels. It examines political institutions (e.g. legislatures, parties, interest groups, courts, constitutions), political processes (e.g. elections, litigation, mass protests, social movements, policy-making), and the influence of politically-relevant ideas (e.g. power, justice, law, equality and inequality, diversity, discrimination) in those contexts, to understand how these elements interact with each other to shape the attitudes and behavior of both individuals and groups in the United States.
