2. A preamble is an introductory and explanatory statement in a document that explains the document's purpose and underlying philosophy. When applied to the opening paragraphs of a statute, it may recite historical facts pertinent to the subject of the statute. It is distinct from the long title or enacting formula of a law.

3. Judicial review is the doctrine in democratic theory under which legislative and executive action is subject to invalidation by the judiciary. Specific courts with judicial review power may annul the acts of the state when it finds them incompatible with a higher authority, such as the terms of a written constitution. Judicial review is an example of the functioning of separation of powers in a modern governmental system (where the judiciary is one of three branches of government). This principle is interpreted differently in different jurisdictions, which also have differing views on the different hierarchy of governmental norms. As a result, the procedure and scope of judicial review differs from country to country and state to state.

4. James Madison (March 16, 1751 – June 28, 1836) was an American politician and political philosopher who served as the fourth President of the United States (1809–1817), and was one of the Founding Fathers of the United States. Considered to be the "Father of the Constitution," he was the principal author of the document. In 1788, he wrote over a third of the Federalist Papers, still the most influential commentary on the Constitution. The first President to have served in the United States Congress, he was a leader in the 1st United States Congress, drafted many basic laws and was responsible for the first ten amendments to the Constitution (said to be based on the Virginia Declaration of Rights), and thus is also known as the "Father of the Bill of Rights". As a political theorist, Madison's most distinctive belief was that the new republic needed checks and balances to protect individual rights from the tyranny of the majority.

5. The Constitution of the United States of America is the supreme law of the United States. It is the foundation and source of the legal authority underlying the existence of the United States of America and the federal government of the United States. It provides the framework for the organization of the United States government and for the relationship of the federal government to the states, to citizens, and to all people within the United States.

6. In the United States, the Bill of Rights is the name by which the first ten amendments to the United States Constitution are known. They were introduced by James Madison to the First United States Congress in 1789 as a series of articles, and came into effect on December 15, 1791, when they had been ratified by three-fourths of the States. Thomas Jefferson was a proponent of the Bill of Rights.

7. Shays' Rebellion was an armed uprising in central and western Massachusetts (mainly Springfield) from 1786 to 1787. The rebellion is named after Daniel Shays, a veteran of the American Revolution who led the rebels, known as "Shaysites" or "Regulators". Most of Shays' compatriots were poor farmers angered by what they felt to be crushing debt and taxes. Failure to repay such debts often resulted in imprisonment in debtor's prisons or the claiming of property by the County.

8. The United States Cabinet (usually referred to as the President's Cabinet or simplified as the Cabinet) is composed of the most senior appointed officers of the executive branch of the federal government of the United States. Its existence dates back to the first American President, George Washington, who appointed a Cabinet of four people (Secretary of State Thomas Jefferson; Secretary of the Treasury Alexander Hamilton; Secretary of War Henry Knox; and Attorney General Edmund Randolph) to advise and assist him in his duties. Cabinet officers are nominated by the President and then presented to the United States Senate for confirmation or rejection by a simple majority. If approved, they are sworn in and begin their duties. Aside from the Attorney General, and previously, the Postmaster General, they all receive the title Secretary. Members of the Cabinet serve at the pleasure of the President.

9. The separation of powers, also known as trials political, is a model for the governance of democratic states. The model was first developed in ancient Greece and came into widespread use by the Roman Republic as part of the unmodified Constitution of the Roman Republic. Under this model, the state is divided into branches or estates, each with separate and independent powers and areas of responsibility. The normal division of estates is into an executive, a legislature, and a judiciary. The separation of powers, also known as trials political, is a model for the governance of democratic states.

10. The Electoral College consists of the popularly elected representatives (electors) who formally elect the President and Vice President of the United States. Since 1964, there have been 538 electors in each presidential election. Article II, Section 1, Clause 2 of the Constitution specifies how many electors each state is entitled to have and that each state's legislature decides how its electors are to be chosen; U.S. territories are not represented in the Electoral College. The Electoral College is an example of an indirect election.
