The federal government of the United States (U.S. federal government or U.S. government) is the national government of the United States.
The United States federal government is composed of three distinct branches: legislative, executive, and judicial. The powers of these three branches are defined and vested by the Constitution of the United States, which has been in continuous effect since March 4, 1789. The powers and duties of these branches are further defined by acts of Congress, including the creation of executive departments and courts subordinate to the Supreme Court of the United States.
In the federal division of power, the federal government shares sovereignty with each of the 50 states in their respective territories. United States law recognizes Indigenous tribes as possessing sovereign powers, while being subject to federal jurisdiction.
State, tribal, and local governments
State governments have the greatest influence over most Americans’ daily lives. The Tenth Amendment prohibits the federal government from exercising any power not delegated to it by the Constitution; as a result, states handle the majority of issues most relevant to individuals within their jurisdiction. Because state governments are not authorized to print currency, they generally have to raise revenue through either taxes or bonds. As a result, state governments tend to impose severe budget cuts or raise taxes any time the economy is falterin.]
Each state has its own written constitution, government, and code of laws. The Constitution stipulates only that each state must have, “a Republican Government”. Therefore, there are often great differences in law and procedure between individual states, concerning issues such as property, crime, health and education, amongst others. The highest elected official of each state is the governor, and in 45 states, a lieutenant governor serves below that position, and is next in the line of succession.
Each state also has an elected state legislature (bicameralism is a feature of every state except Nebraska), whose members represent the voters of the state. Each state maintains its own state court system. In some states, supreme and lower court justices are elected by the people; in others, they are appointed, as they are in the federal system.
As a result of the Supreme Court case Worcester v. Georgia, American Indian tribes are considered “domestic dependent nations” that operate as sovereign governments subject to federal authority but, in some cases, outside of the jurisdiction of state governments. Hundreds of laws, executive orders and court cases have modified the governmental status of tribes vis-à-vis individual states, but the two have continued to be recognized as separate bodies. Tribal governments vary in robustness, from a simple council used to manage all aspects of tribal affairs, to large and complex bureaucracies with several branches of government. Tribes are currently encouraged to form their own governments, with power resting in elected tribal councils, elected tribal chairpersons, or religiously appointed leaders (as is the case with pueblos). Tribal citizenship and voting rights are typically restricted to individuals of native descent, but tribes are free to set whatever citizenship requirements they wish.
The institutions that are responsible for local government within states are typically counties, municipalities, and special-purpose districts, which make laws that affect their particular area. These laws concern issues such as traffic, the sale of alcohol and the keeping of animals. A county is an administrative or political subdivision of a state, while Louisiana and Alaskahave county-equivalent subdivisions called parishes and boroughs, respectively. The specific governmental powers of counties vary widely between the states, with those in Connecticut, Rhode Island, and some parts of Alaska and Massachusetts having little or no power, existing only as geographic distinctions. In other areas, county governments have more power, such as to collect taxes and maintain law enforcement agencies. Twenty states further divide their counties into civil townships. Population centers may be organized into incorporated municipalities of several types, including the city, town, borough, and village. These municipal entities also vary from state to state, and typically subordinate to the government of a county or civil township. However, many rural and suburban regions are in unincorporated areas that have no municipal government below the county or civil township level. Certain cities have consolidated with their county government to form consolidated city-counties, or have been legally separated from counties altogether to form independent cities. States may also create special-purpose districts that perform a single function or a set of related functions within an area inside one or more counties or municipalities, like school districts, water management districts, fire management districts, and library districts.
Separate powers
The House and Senate each have particular exclusive powers. For example, the Senate must approve (give “advice and consent” to) many important presidential appointments, including cabinet officers, federal judges (including nominees to the Supreme Court), department secretaries (heads of federal executive branch departments), U.S. military and naval officers, and ambassadors to foreign countries. All legislative bills for raising revenue must originate in the House of Representatives. The approval of both chambers is required to pass all legislation, which then may only become law by being signed by the president (or, if the president vetoes the bill, both houses of Congress then re-pass the bill, but by a two-thirds majority of each chamber, in which case the bill becomes law without the president’s signature). The powers of Congress are limited to those enumerated in the Constitution; all other powers are reserved to the states and the people.
The Constitution also includes the Necessary and Proper Clause, which grants Congress the power to “make all laws which shall be necessary and proper for carrying into execution the foregoing powers”. Members of the House and Senate are elected by first-past-the-post voting in every state except Louisiana and Georgia, which have runoffs, and Maine and Alaska, which use ranked-choice voting.
