Politics

The United States of America consists of 50 states with limited autonomy in which federal law takes precedence over state law. In general, matters that lie entirely within state borders are the exclusive concern of state governments. These include internal communications; regulations relating to property, industry, business, and public utilities; the state criminal code; and working conditions within the state. Many state laws are quite similar from state to state. Finally, there are many areas of overlap between state and federal jurisdictions.
In recent years, the federal government has assumed broader responsibility in such matters as health, education, welfare, transportation, and housing and urban development. 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. On such matters as the operation of businesses, banks, public utilities, and charitable institutions, state constitutions are often more detailed and explicit than the federal constitution.
The federal government itself consists of three branches: the executive branch, the legislative branch, and the judicial branch. The head of the executive branch is the President of the United States. The legislative branch consists of the United States Congress, while the Supreme Court of the United States is the head of the judicial branch. The President is elected to a four year term by the U.S. Electoral College. The various electors are in turn chosen primarily by the popular votes in the 50 states and the District of Columbia. Members of Congress are elected at varying dates, as are state Governors and state legislatures.
The federal and state government is dominated by two political parties, the Republicans and the Democrats. The dominant political culture in the United States is, as a whole, somewhat to the right of the dominant political culture in European democracies. Given their complex support bases it is difficult to specifically categorise the two major parties' appeal. Within the US political culture, the Republican Party is described as center-right and the Democratic Party is described as center-left. Minor party and independent candidates are very occasionally elected, usually to local or state office, but the United States political system has historically supported "catch all parties" rather than coalition governments. The ideology and policies of the sitting President of the United States commonly play a large role in determining the direction of his political party, as well as the platform of the opposition.
The two parties exist on both the state and federal level, although the parties' organization, platform, and ideologies are not necessarily uniform across all levels of government.
Both major parties draw some support from all the diverse socio-economic classes which compose the mature multi-ethnic capitalist society which makes up the United States. Business interests provide the major funding and support to the Republican Party while labor unions and minority ethnic groups provide major support to the Democrats. Access to funds is vital in the political system due to the financial costs of mounting political campaigns. Thus, through lobbying, corporations, unions, and other organized groups that provide funds and political support to parties and politicians can play a large role in determining the political agendas and government decision-making.

At the time of the Declaration of Independence, the United States consisted of 13 states. In the following years, this number has grown steadily due to expansion to the west, conquest and purchase of lands by the American government, and division of existing states to the current number of 50:
