Which document outlines the powers and limits of the U.S. Presidency?

The U.S. Constitution is the foundational document that outlines the structure of the federal government, including the powers and limits of the presidency. Article II specifically delineates the executive branch, detailing the president's powers such as serving as the commander in chief of the armed forces, executing federal laws, and conducting foreign affairs. It also specifies the limits of these powers, including provisions for impeachment and the constraints imposed by checks and balances, ensuring that no single branch of government, including the presidency, becomes too powerful. This framework establishes the legal and constitutional authority of the executive, making the Constitution the key document governing presidential powers.

Other documents, like the Declaration of Independence, primarily address the reasons for America’s separation from Great Britain and do not outline government structure or powers. The Bill of Rights focuses on individual freedoms and rights rather than the powers of the presidency. The Federalist Papers, while offering insights into the framers' intentions regarding government structure, are essentially essays in support of ratifying the Constitution and do not serve as governing documents themselves. Therefore, the Constitution stands as the definitive source for the powers and limits of the U.S. presidency.
