The United States operates under a federal system with three branches of government: executive, legislative, and judicial. The President leads the executive branch, responsible for implementing laws and foreign policy. The legislative branch, composed of Congress (Senate and House of Representatives), creates laws, controls spending, and can declare war.

The Supreme Court heads the judicial branch, interpreting laws for constitutionality. Two main political parties, Democrats and Republicans, hold differing views on healthcare, taxes, immigration, and climate change.

U.S. politics is influenced by media, interest groups, and social media. Despite its complexity, it remains a dynamic arena for democratic debate and governance.
