Government. The United States is a federal republic composed of a national government and fifty state governments. The political system is dominated by two parties: the Republicans and the Democrats. One of the features of American democracy is low voter turnout. On the average, less than half the eligible voters participate in federal elections.
Also referred to as conservatives and liberals, respectively, Republicans and Democrats differ on certain key social issues. Republicans are generally conservative on social spending and moral issues. They support cuts in federally-sponsored social programs such as welfare. They believe in strengthening institutions such as marriage and the traditional family and usually are opposed to abortion and gay rights. Democrats tend to support federal funding for social programs that favor minorities, the environment, and women's rights. However, critics argue that these two parties set a very narrow range for political debate. Third parties that have emerged on both the left and the right include the Green, Socialist, Farm-Labor, Reform, and Libertarian parties.
