American politics is the set of political processes, institutions, conflicts, and practices that govern the United States of America. It encompasses electoral competition, policymaking, administrative implementation, judicial review, and civic engagement among actors such as presidents, members of United States Congress, state governors, local officials, political parties, interest groups, and social movements. Debates often revolve around constitutional interpretation, federalism, civil rights, economic regulation, and foreign policy decisions involving actors like Department of State (United States), Department of Defense (United States), and international agreements.

History

The origins trace to events like the American Revolution and the drafting of the United States Constitution after the Articles of Confederation era, with Federalists and Anti-Federalists shaping early practice alongside figures such as George Washington, James Madison, and Alexander Hamilton. Antebellum tensions over slavery produced crises like the Missouri Compromise and the Compromise of 1850, culminating in the American Civil War and Reconstruction policies administered under presidents like Abraham Lincoln and Andrew Johnson. The Progressive Era saw reforms influenced by leaders such as Theodore Roosevelt and lawmakers tied to legislation exemplified by the Pure Food and Drug Act; the New Deal under Franklin D. Roosevelt expanded federal roles through programs like the Social Security Act. Cold War dynamics framed presidencies of Harry S. Truman, Dwight D. Eisenhower, John F. Kennedy, and Richard Nixon and shaped institutions including the Central Intelligence Agency and treaties like the North Atlantic Treaty. Civil rights campaigns led by Martin Luther King Jr. and legislation such as the Civil Rights Act of 1964 transformed party coalitions, while late 20th and early 21st century developments—including the presidencies of Ronald Reagan, Bill Clinton, George W. Bush, Barack Obama, Donald Trump, and Joe Biden—altered regulatory regimes, judicial appointments to the Supreme Court of the United States, and electoral strategies.

Political Institutions

Key national institutions include the United States Congress (bicameral: United States Senate and United States House of Representatives), the President of the United States, and the federal judiciary culminating in the Supreme Court of the United States. Administrative agencies such as the Internal Revenue Service, Federal Reserve System, Environmental Protection Agency, and Federal Bureau of Investigation implement statutes passed by legislatures and enforced by executives. Constitutional checks and balances derive from documents like the United States Constitution and practices settled by precedents such as Marbury v. Madison; major structural rules include the Electoral College (United States), life tenure for federal judges confirmed by the United States Senate, and impeachment processes used against figures such as Andrew Johnson and Bill Clinton. Congressional committees, Senate rules like the filibuster, and executive instruments like executive orders shape governance.

Political Parties and Elections

Contemporary competition centers on party organizations like the Democratic Party (United States) and Republican Party (United States), with third parties including the Libertarian Party (United States) and Green Party (United States). Primary systems—open, closed, and caucus models—determine nominations in contests such as the Iowa caucuses and New Hampshire primary. Campaign finance is regulated by statutes and institutions such as the Federal Election Commission and decisions like Citizens United v. Federal Election Commission have reshaped spending by entities including Political action committees and super PACs. Voting rights controversies engage laws like the Voting Rights Act of 1965 and state practices such as voter ID laws, while landmark elections (e.g., 2000 United States presidential election) have prompted litigation at the Supreme Court of the United States and recounts administered by secretaries of state.

Public Policy and Government Programs

Policy arenas involve taxation, social welfare, healthcare, education, and national security executed through statutes such as the Affordable Care Act and programs like Medicare (United States) and Medicaid. Economic policy is influenced by entities including the Federal Reserve System and legislation like the Tax Cuts and Jobs Act of 2017; regulatory policy involves agencies such as the Securities and Exchange Commission and the Environmental Protection Agency. Social policy debates engage landmark rulings such as Roe v. Wade and pieces of legislation like the No Child Left Behind Act, while criminal justice reform and sentencing laws intersect with institutions such as state Department of Corrections systems and federal prosecutors. Foreign policy decisions reference alliances like NATO and conflicts including Iraq War and negotiations such as the Iran nuclear deal framework.

Political Culture and Public Opinion

Public attitudes are measured by organizations like Pew Research Center, Gallup (company), and academic studies from institutions such as Harvard University and University of Chicago. Cultural cleavages often follow geography illustrated by voting patterns in New England, the Sun Belt, the Rust Belt, and the Deep South; demographic factors include race, religion, education levels, and urban-rural divides involving cities such as New York City and Los Angeles. Civic movements—ranging from Women's suffrage to Black Lives Matter and Tea Party movement—shape agenda-setting, while polarization debates reference scholars and cases centering on the role of media ecosystems like Fox News and MSNBC as well as social platforms like Facebook (now Meta Platforms, Inc.) and Twitter (now X).

Interest Groups and Media

Interest groups include organized labor such as the AFL–CIO, business associations like the Chamber of Commerce (United States), advocacy organizations like American Civil Liberties Union and National Rifle Association, and sectoral groups such as National Education Association. Lobbying is regulated under statutes like the Lobbying Disclosure Act with disclosures to bodies including the United States Senate and United States House of Representatives. Mass media outlets—The New York Times, The Washington Post, Fox News, CNN, NPR—and digital platforms influence agendas, while investigative reports by entities like ProPublica prompt congressional hearings and Department of Justice inquiries. Political advertising, campaign strategy firms, and polling organizations mediate between interest groups and electorates.

Federalism and State Politics

Power divisions between the federal government and the states are grounded in the Tenth Amendment to the United States Constitution and disputes often adjudicated by the Supreme Court of the United States in cases like McCulloch v. Maryland. State governments—governors, state legislatures, and state courts—implement policy variations seen in disparate approaches such as California's climate regulations versus Texas's regulatory framework. Intergovernmental grants, block grants, and mandates from agencies like the Department of Education (United States) shape fiscal federalism, while state-level innovations in areas like election administration, health policy, and criminal justice produce laboratories referenced in academic literature and by organizations such as the National Governors Association.
