The United States is a federal constitutional republic, in which the President of the United States (the head of state and head of government), Congress, and judiciary share powers reserved to the national government, and the federal government shares sovereignty with the state governments.
The executive branch is headed by the President and is independent of the legislature. Legislative power is vested in the two chambers of Congress: the Senate and the House of Representatives. The judicial branch (or judiciary), composed of the Supreme Court and lower federal courts, exercises judicial power. The judiciary’s function is to interpret the United States Constitution and federal laws and regulations. This includes resolving disputes between the executive and legislative branches. The federal government’s layout is explained in the Constitution. Two political parties, the Democratic Party and the Republican Party, have dominated American politics since the American Civil War, although other parties have also existed.
There are major differences between the political system of the United States and that of most other developed democracies. These include increased power of the upper house of the legislature, a wider scope of power held by the Supreme Court, the separation of powers between the legislature and the executive, and the dominance of only two main parties. The United States is one of the world’s developed democracies where third parties have the least political influence.
The federal entity created by the U.S. Constitution is the dominant feature of the American governmental system. However, most residents are also subject to a state government, and also subject to various units of local government. The latter can include counties, municipalities, and special districts.
Mayor-Council
This is the oldest form of city government in the United States and, until the beginning of the 20th century, was used by nearly all American cities. Its structure is like that of the state and national governments, with an elected mayor as chief of the executive branch and an elected council that represents the various neighborhoods forming the legislative branch. The mayor appoints heads of city departments and other officials, sometimes with the approval of the council. He or she has the power of veto over ordinances (the laws of the city) and often is responsible for preparing the city’s budget. The council passes city ordinances, sets the tax rate on property, and apportions money among the various city departments. As cities have grown, council seats have usually come to represent more than a single neighborhood.
The Commission
This combines both the legislative and executive functions in one group of officials, usually three or more in number, elected city-wide. Each commissioner supervises the work of one or more city departments. Commissioners also set policies and rules by which the city is operated. One is named chairperson of the body and is often called the mayor, although his or her power is equivalent to that of the other commissioners.[3]
Council-Manager
The city manager is a response to the increasing complexity of urban problems that need management ability not often possessed by elected public officials. The answer has been to entrust most of the executive powers, including law enforcement and provision of services, to a highly trained and experienced professional city manager.
The city manager plan has been adopted by a large number of cities. Under this plan, a small, elected council makes the city ordinances and sets policy, but hires a paid administrator, also called a city manager, to carry out its decisions. The manager draws up the city budget and supervises most of the departments. Usually, there is no set term; the manager serves as long as the council is satisfied with his or her work.
County government
The county is a subdivision of the state, sometimes (but not always) containing two or more townships and several villages. New York City is so large that it is divided into five separate boroughs, each a county in its own right. On the other hand, Arlington County, Virginia, the United States’ smallest county, located just across the Potomac River from Washington, D.C., is both an urbanized and suburban area, governed by a unitary county administration. In other cities, both the city and county governments have merged, creating a consolidated city–county government.
In most U.S. counties, one town or city is designated as the county seat, and this is where the government offices are located and where the board of commissioners or supervisors meets. In small counties, boards are chosen by the county; in the larger ones, supervisors represent separate districts or townships. The board collects taxes for state and local governments; borrows and appropriates money; fixes the salaries of county employees; supervises elections; builds and maintains highways and bridges; and administers national, state, and county welfare programs. In very small counties, the executive and legislative power may lie entirely with a sole commissioner, who is assisted by boards to supervise taxes and elections. In some New England states, counties do not have any governmental function and are simply a division of land.
Town and village government
Thousands of municipal jurisdictions are too small to qualify as city governments. These are chartered as towns and villages and deal with local needs such as paving and lighting the streets, ensuring a water supply, providing police and fire protection, and waste management. In many states of the US, the term town does not have any specific meaning; it is simply an informal term applied to populated places (both incorporated and unincorporated municipalities). Moreover, in some states, the term town is equivalent to how civil townships are used in other states.
The government is usually entrusted to an elected board or council, which may be known by a variety of names: town or village council, board of selectmen, board of supervisors, board of commissioners. The board may have a chairperson or president who functions as chief executive officer, or there may be an elected mayor. Governmental employees may include a clerk, treasurer, police and fire officers, and health and welfare officers.
One unique aspect of local government, found mostly in the New England region of the United States, is the town meeting. Once a year, sometimes more often if needed, the registered voters of the town meet in open session to elect officers, debate local issues, and pass laws for operating the government. As a body, they decide on road construction and repair, construction of public buildings and facilities, tax rates, and the town budget. The town meeting, which has existed for more than three centuries in some places, is often cited as the purest form of direct democracy, in which the governmental power is not delegated, but is exercised directly and regularly by all the people.
