Politics of the United States takes place in the framework of a presidential,federal republic where the President of the United States (the head of state and head of government),United States Congress,and judiciary share federal powers,and the federal government shares sovereignty with the state governments.Federal and state elections operate as a two-party electoral system.
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.Judicial power is exercised by the judicial branch (or judiciary),composed of the Supreme Court and lower federal courts.The judiciary's function is to interpret the United States Constitution as well as federal laws and regulations.This includes resolving disputes between the executive and legislative branches.The federal government of the United States was established by the Constitution.American politics has been dominated by two parties,the Democratic Party and the Republican Party,since the American Civil War,although other parties have also existed.
Major differences between the political system of the United States and that of most other developed democracies are the power of the Senate as the upper house of the legislature,the wide scope of power of the Supreme Court,the separation of powers between the legislature and the executive government,and the dominance of the two main parties 鈥 the United States being one of the world's developed democracies in which third parties have the least political influence.
The federal entity created by the Constitution is the dominant feature of the American governmental system.However,most persons are also subject to a state government,and all are subject to various units of local government.The latter include counties,municipalities,and special districts.
This multiplicity of jurisdictions reflects the country's history.The federal government was created by the states,which as colonies were established separately and governed themselves independently of the others.Units of local government were created by the colonies to efficiently carry out various state functions.As the country expanded,it admitted new states modeled on the existing ones.
State government
Before their independence,colonies governed themselves separately under the authority of the British Crown.In the early years of the republic,prior to the adoption of the Constitution,each state was virtually autonomous.The delegates to the Constitutional Convention sought a stronger,more viable federal union while preserving the sovereignty of the states.
States governments have the power to make law on all subjects that are not granted to the national government or denied to the states in the U.S.Constitution.These include education,family law,contract law,and most crimes.Unlike the national government,which only has those powers granted to it in the Constitution,a state government has inherent powers allowing it to act unless limited by a provision of the state or national constitution.
Like the national government,state governments have three branches:executive,legislative,and judicial.The chief executive of a state is its popularly elected governor,who typically holds office for a four-year term (although in a few states the term is two years).Except for Nebraska,which has one-chamber legislature (known as a unicameral legislature),all states have a bicameral legislature,with the upper house usually called the Senate and the lower house called the House of Representatives,the House of Delegates,Assembly or something similar.In most states,senators serve four-year terms,and members of the lower house serve two-year terms.
The constitutions of the various states differ in some details but generally follow a pattern similar to that of the federal Constitution,including a statement of the rights of the people and a plan for organizing the government.State constitutions are generally more detailed,however.
Local government
There are 87,000 local governments,including 3,034 counties,19,498 municipalities,16,500 townships,13,500 school districts,and 35,000 other special districts which deal with issues like fire protection.[1] To a greater extent than on the federal or state level,the local governments directly serve the needs of the people,providing everything from police and fire protection to sanitary codes,health regulations,education,public transportation,and housing.
About 28% of the people live in cities of 100,000 or more population.City governments are chartered by states,and their charters detail the objectives and powers of the municipal government.For most big cities,cooperation with both state and federal organizations is essential to meeting the needs of their residents.
Types of city governments vary widely across the nation.However,almost all have some kind of central council,elected by the voters,and an executive officer,assisted by various department heads,to manage the city's affairs.
There are three general types of city government:the mayor-council,the commission,and the council-manager.These are the pure forms; many cities have developed a combination of two or three of them.
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 similar to 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 鈥 the laws of the city 鈥 and frequently 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.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.
Council-Manager.The city manager is a response to the increasing complexity of urban problems,which require management expertise 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 鈥 but not always 鈥 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,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 as a whole; 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.
