Politics of the United States There are a few major differences between the political system of the United States and that of most other developed democracies. These include greater power in 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. Third parties have less political influence in the United States than in other democratically run developed countries; this is because of a combination of stringent historic controls. These controls take shape in the form of state and federal laws, informal media prohibitions, and winner-take-all elections, and include ballot access issues and exclusive debate rules.
