The Executive Branch Decoded
On September 14, 2001, Congress passed the Authorization for Use of Military Force. It was sixty words long. It granted the president authority to use “all necessary and appropriate force” against those responsible for the September 11 attacks. That single sentence has been cited to justify military operations in at least fourteen countries across two decades, under four different presidents from both parties. No one who voted for it imagined it would still be in force a quarter century later. But executive power does not work on imagination. It works on precedent. Once authority is claimed and unchallenged, it becomes the new baseline—and the next expansion starts from there. The 2001 AUMF is not an anomaly. It is the clearest modern example of a pattern that has been operating since the founding: power flows toward wherever it can be exercised most efficiently, and in a system with 535 legislators and one executive, efficiency has a permanent address.
The Constitutional Design
The Founders’ vision was explicit. Article II of the Constitution creates an executive whose core function is to “take care that the laws be faithfully executed.” Not to make the laws. Not to interpret them. To carry them out. The president would serve as commander in chief, but the power to declare war belonged to Congress. The president could appoint officials, but only with the Senate’s advice and consent. The veto power existed as a defensive check against bad legislation, not as a tool for driving policy.
Alexander Hamilton, in Federalist No. 69, went to considerable lengths to distinguish the proposed presidency from the British monarchy. The president would have no power to create courts, no authority over commerce, no ability to enact legislation unilaterally. The office was deliberately constrained because the Founders understood, from hard experience with King George III, what concentrated executive power produces.
The reality today would be unrecognizable to them. The modern president drives the legislative agenda, conducts military operations without congressional authorization, issues executive orders that function as legislation, and presides over an administrative state of more than two million civilian employees making binding rules with the force of law. The gap between design and reality is not small. It is a different system wearing the same name.
The Ratchet Mechanism
Executive power expands through a specific mechanism that the political scientist Robert Higgs called the “ratchet effect.” The pattern is consistent across centuries: a crisis arrives, the president claims expanded authority to address it, the crisis eventually subsides, but the authority does not fully retract. Each crisis leaves the baseline of executive power higher than it was before.
Lincoln suspended habeas corpus and created military tribunals during the Civil War. The specific powers lapsed, but the precedent that a president could take extraordinary action during domestic emergency persisted. Franklin Roosevelt massively expanded the executive branch during the Great Depression and the Second World War, creating agencies and programs that outlived both crises. The internment of Japanese Americans, price controls, the wartime command economy—the specific programs ended, but the institutional infrastructure and the claim to sweeping emergency authority remained.
The post-9/11 expansion followed the same arc. The Patriot Act expanded surveillance authority. Guantánamo Bay and “enhanced interrogation” asserted executive power over detention and treatment of prisoners. Two decades later, the surveillance infrastructure is larger, not smaller, and the AUMF still provides legal cover for operations the original authors never contemplated. COVID-19 added another ratchet turn: public health emergency powers expanded executive authority over commerce, movement, and institutional operations on a scale not seen since wartime.
In other words, the ratchet only turns one way. Crises create the political conditions for expansion—urgency, fear, the demand that someone act immediately. Retrenchment requires deliberate political effort against an executive who now possesses and wants to keep the expanded powers. The asymmetry is decisive.
Executive Orders and the Administrative State
Executive orders are not mentioned in the Constitution. They have become one of the presidency’s most powerful instruments. When Congress is gridlocked—which, in an era of deep polarization, is most of the time—presidents legislate through executive action. Courts rarely strike these orders down. Congress can override them only with a veto-proof majority, which polarization makes nearly impossible. The next president can reverse them, but rarely reverses everything, and some orders create facts on the ground that cannot be undone.
The administrative state amplifies this dynamic. Congress passes broad statutes—“regulate in the public interest,” “ensure workplace safety,” “protect the environment”—and delegates the details to executive agencies. The EPA, FDA, FCC, SEC, and dozens of other agencies fill in those details through rulemaking. These rules carry the force of law. And the agencies answer to the president.
The legal scholar Adrian Vermeule has noted that this delegation effectively transfers legislative power to the executive under the cover of administrative expertise. Congress sets vague mandates; the executive decides what they actually mean. The details are where policy lives, and the executive controls the details. In other words, Congress writes the headlines, and the president writes the fine print. And the fine print is what people actually experience as law.
War Powers: The Abandoned Check
The Constitution is unambiguous: Congress declares war. The last time Congress formally declared war was 1941, against the Axis powers in World War II. Since then, the United States has conducted major military operations in Korea, Vietnam, Laos, Cambodia, Grenada, Panama, Iraq (twice), Afghanistan, Libya, Syria, Somalia, Yemen, and elsewhere—all without a declaration of war.
The War Powers Resolution of 1973, passed in the wake of Vietnam, was supposed to reassert congressional authority. It requires the president to notify Congress within 48 hours of committing armed forces and to withdraw them within 60 days without congressional authorization. In practice, presidents from both parties have treated the resolution as advisory. They notify Congress but do not request authorization. Congress protests but does not cut funding. The resolution created the appearance of a check without the substance of one.
The incentive structure explains why. A president who acts militarily and succeeds gets credit. A president who defers to Congress and delays action while Congress debates gets blamed for inaction. Members of Congress, individually, prefer not to vote on military action—a vote creates accountability. It is easier to let the president act and then either support or criticize the outcome from a safe distance. Everyone’s incentives align with presidential unilateralism. No one’s incentives favor institutional restraint.
The Incentive Architecture
Understanding why the executive expands requires understanding what each actor in the system is optimized for. Presidents want to accomplish things—to build a legacy, to deliver wins for their party, to be seen as effective. Executive action is faster than legislation. Using it is rewarded. Not using it is punished. The public holds the president responsible for outcomes regardless of whether those outcomes fall within constitutional authority. When a crisis occurs, the question is never “Why didn’t the president respect constitutional limits and let Congress handle it?” It is always “Why didn’t the president do something?”
Congress faces parallel incentives that point the same direction. Delegation lets members avoid hard votes—let the EPA decide emission standards so no senator has to take a position that angers either industry or environmentalists. Polarization makes legislation difficult, which creates a vacuum the executive fills. And partisan loyalty means a Congress controlled by the president’s party will not check a same-party president, while an opposition Congress lacks the votes to override vetoes.
Courts defer to the executive on national security, invoke the political question doctrine (the judicial principle that some disputes between branches are non-justiciable and should be resolved through political processes rather than litigation) to avoid inter-branch conflicts, and face standing and timing barriers that make it difficult to check executive overreach in real time. By the time a case reaches the Supreme Court, the executive action has often already been implemented, creating facts on the ground that judges are reluctant to undo.
In other words, every institutional actor in the system—the president, Congress, the courts—faces incentives that favor executive expansion. No actor faces strong incentives to enforce restraint. The system does not produce imperial presidencies because individual presidents are power-hungry. It produces them because the incentive architecture selects for expansion and punishes restraint.
Who Becomes President
The selection process compounds the structural dynamics. Winning the presidency requires extraordinary personal ambition, the ability to raise billions of dollars from concentrated interests, mastery of simplified messaging that wins primaries and general elections, and the charisma to dominate a personality-driven media landscape. Self-effacing people who believe in institutional constraints do not run for president. People who believe they should have vast power do.
What the process does not select for is equally revealing: constitutional humility, willingness to share power, nuanced policy understanding, or comfort with inaction when inaction is the appropriate response. The selection filter is precise. It identifies individuals who want power, gives them power, and surrounds them with structural incentives to accumulate more. The outcome is not a mystery.
The Accountability Paradox
The president occupies a strange position in the accountability landscape. On one hand, the office is the most visible and most scrutinized in the country—the only official elected by the entire nation. On the other hand, the president cannot be fired except through impeachment, which requires a two-thirds Senate vote and has never resulted in removal. Four-year terms insulate the president from immediate electoral consequences, and second-term presidents face no electoral accountability at all.
Meaningful accountability would require voters to attribute outcomes to presidential actions, understand the counterfactuals (what would have happened under different policies), and vote accordingly. This assumption is, to put it gently, optimistic. The information asymmetry between what a president does and what voters understand about what a president does is enormous. Executive actions that overreach constitutional limits are often invisible to the public, while inaction during a crisis is immediately and viscerally apparent.
This creates a permanent asymmetry: the political cost of overreach is low and delayed. The political cost of inaction is high and immediate. A system that rewards action and punishes restraint will, over time, produce more action and less restraint. That is precisely what has happened.
How This Was Decoded
Synthesized from constitutional text and Federalist Papers analysis, Robert Higgs’s ratchet-effect framework for crisis-driven government growth, historical case studies of executive expansion from Lincoln through post-9/11 national security policy, Adrian Vermeule’s work on administrative law and executive power, and institutional incentive analysis across the executive, legislative, and judicial branches. Cross-verified by confirming that the same expansion pattern appears regardless of party, ideology, or era—the mechanism is structural rather than ideological. The system does not need conspiratorial actors. It needs only incentive alignment, and the incentives have aligned in favor of executive expansion for two and a half centuries.
