There are five principles of government in the United States. These guiding principles of the U.S. Government were considered essential by the Founding Fathers in preserving liberty and equality of the people while also preventing abuses of power by the government. Popular sovereignty dictates that the government only operates with the people's consent and authority, while the principle of limited government means that the government's powers and functions are restricted and described in the U.S. Constitution. The principles of separation of powers and checks and balances can be seen the lawmaking process in the U.S. For example, Congress has the power to pass a bill with a majority vote. The president can then sign the bill into law. However, the president is also able to veto that bill, providing a limit on the power of Congress. The Congress, however, can override his veto with a two-thirds majority vote. The judicial branch has the power to check both the legislative and executive branches in being able to determine that a law is unconstitutional. The final guiding principle of the U.S. Government is federalism. Federalism is the division of power seen between the federal government and state governments. The federal government has the power to print money so that it is uniform across the country while state governments have their own unique powers as well.
