Modern presidents are CEOs with broad powers over the federal government.

The United States Constitution lays out three hypothetically equal branches of government—the executive, the legislative, and the judicial—but over the years, the president, as head of the executive branch, has emerged as the usually dominant political and administrative force at the federal level. In fact, Daniel Gitterman tells us, the president is, effectively, the CEO of an enormous federal bureaucracy.

Using the unique legal authority delegated by thousands of laws, the ability to issue executive orders, and the capacity to shape how federal agencies write and enforce rules, the president calls the shots as to how the government is run on a daily basis. Modern presidents have, for example, used the power of the purchaser to require federal contractors to pay a minimum wage and to prohibit contracting with companies and contractors that knowingly employ unauthorized alien workers.

Presidents and their staffs use specific tools, including executive orders and memoranda to agency heads, as instruments of control and influence over the government and the private sector. For more than a century, they have used these tools without violating the separation of powers. Calling the Shots demonstrates how each of these executive powers is a powerful weapon of coercion and redistribution in the president's political and policymaking arsenal.
