The presidency & executive branch
The constitutional powers, limits, and structure of the US presidency and executive branch, from Article II to the modern administrative state—tuned for the FSOT.
The Vesting Clause and Article II Powers
Article II, Section 1 of the Constitution opens with the Vesting Clause: "The executive Power shall be vested in a President of the United States of America." Unlike Article I, which grants Congress only powers "herein granted," Article II's grant is unqualified—the textual hook for theories of broad inherent executive authority. The President must be a natural-born citizen, at least 35 years old, and a resident for 14 years. The Twenty-Second Amendment (ratified 1951, a response to Franklin D. Roosevelt's four terms) caps service at two elected terms.
The enumerated powers are concentrated and consequential. Article II, Section 2 makes the President Commander in Chief of the armed forces; grants the power to make treaties (with two-thirds Senate concurrence) and to appoint ambassadors, judges, and officers (with Senate advice and consent); and confers the pardon power for federal offenses, which is plenary except in cases of impeachment. Section 3 requires the President to "take Care that the Laws be faithfully executed"—the Take Care Clause—and to deliver the State of the Union, recommend measures, and receive ambassadors (the basis for recognizing foreign governments).
Selection, Succession, and the Cabinet
The President is chosen not by popular vote but by the Electoral College (Article II, Section 1, as modified by the Twelfth Amendment of 1804, which separated presidential and vice-presidential balloting after the 1800 Jefferson–Burr deadlock). A candidate needs 270 of 538 electoral votes; the House decides contingent elections voting by state delegation, as in 1824 (John Quincy Adams).
The Twenty-Fifth Amendment (ratified 1967, after the Kennedy assassination) codifies succession and disability: Section 1 confirms the Vice President succeeds; Section 2 lets the President fill a vice-presidential vacancy (used when Gerald Ford replaced Spiro Agnew in 1973); Sections 3 and 4 govern temporary and involuntary transfers of power. The Cabinet—heads of the 15 executive departments—holds no independent constitutional power; it serves at the President's pleasure, a principle traced to the Decision of 1789 in the First Congress establishing presidential removal of department heads.
The Administrative State
The modern executive branch dwarfs the framers' design: roughly 2 million civilian employees across departments and independent agencies. The Executive Office of the President, created by Reorganization Act of 1939, includes the Office of Management and Budget and the National Security Council (established by the National Security Act of 1947). Independent regulatory commissions such as the Federal Reserve and the SEC exercise quasi-legislative and quasi-judicial authority, their commissioners protected from at-will removal—a structure the Supreme Court upheld in Humphrey's Executor v. United States (1935) but has narrowed in Seila Law v. CFPB (2020) and Collins v. Yellen (2021).
