The form of government established in the U.S. Constitution is sometimes called a representative or indirect democracy.
...
Republic: A form of government in which the people are sovereign (ultimate source of power) and give their consent to representatives to make laws. The term, republic, comes from the Latin res publicae, meaning “thing of the people.”
...
Checks and Balances: Constitutional powers are distributed among the branches of government allowing each to limit the application of power of the other branches and to prevent expansion of power of any branch.
Consent of the Governed/Popular Sovereignty: The power of government comes from the people.
Due Process: The government must interact with all people according to the duly-enacted laws and apply these rules equally with respect to all people.
Equality: All individuals have the same status regarding their claim as human beings to natural rights and treatment under the law.
Federalism: The people delegate certain powers to the national government, while the states retain other powers; and the people, who authorize both the states and national government, retain all freedoms not delegated to the governing bodies.
Freedom of contract: Freedom of individuals and corporations to make legally binding mutual agreements without arbitrary or unreasonable legal restrictions
Freedom of religion: The right to choose one’s religion or form of worship, if any, without interference; freedom of conscience
Freedom of speech, press, and assembly: The legal right to express one’s opinions freely, orally or in writing, and the right to gather with others in groups of one’s choice without arbitrary or unreasonable restrictions.
Liberty: Except where authorized by citizens through the Constitution, government does not have the authority to limit freedom.
Limited Government: Citizens are best able to pursue happiness when government is confined to those powers which protect their life, liberty, and property.
Majority Rule/Minority Rights: Laws may be made with the consent of the majority, subject to the limitation that those laws do not infringe on the inalienable rights of the minority.
Natural/Inalienable Rights: Rights which belong to us by nature and can only be justly abridged through due process. Examples are life, liberty, property, and the pursuit of happiness.
Private Property: The natural rights of all individuals to create, obtain, and control their possessions, beliefs, faculties, and opinions, as well as the fruits of their labor.
Rule of Law: Government and citizens all abide by the same laws regardless of political power. Those laws are justly applied, consistent with an ethos of liberty, and stable.
