Why do governments exist? One major reason is that they create rules. But what rules are necessary or desirable? That is open to question, and different types of governments have certainly created a wide variety of rules.

Democracies are based on "rule of law." The ancient Greeks (particularly Aristotle) valued natural law, the notion that human societies should be governed by ethical principles found in nature.

Liberty and equality. These words represent basic values of democratic political systems, including that of the United States. Rule by absolute monarchs and emperors has often brought peace and order, but at the cost of personal freedoms. Democratic values support the belief that an orderly society can exist in which freedom is preserved. But order and freedom must be balanced.

The American colonies began developing a democratic tradition during their earliest stages of development. Over 150 years later, the colonists believed their experience was great enough to refuse to recognize the British king. The first decade was rocky. The American Revolution and the domestic instability that followed prompted a call for a new type of government with a constitution to guarantee liberty. The constitution drafted in the early days of the independent American republic has endured longer than any in human history.

The great expanse of the Atlantic Ocean created a safe distance for American colonists to develop skills to govern themselves. Despite its efforts to control American trade, England could not possibly oversee the entire American coastline. Colonial merchants soon learned to operate outside British law. Finally, those who escaped religious persecution in England demanded the freedom to worship according to their faiths.

So the freedom that the American Revolution sought to preserve proved to create a government under the Articles of Confederation that could not keep law and order. But the failure of the initial experiment helped the founders to find a more perfect balance between liberty and order in the Constitution they produced in 1787.

Most of the delegates at the Constitutional Convention had already risked being hanged as traitors by the British. No wonder that they worried about their states' reactions to their decision to abandon the Articles of Confederation and create a whole new document.

States cherished their new freedom from British control, and ratification of the Constitution by state legislatures was by no means certain. All thirteen states finally ratified by 1790, but only with the addition of ten amendments, known as the Bill of Rights, that guaranteed citizens' rights and freedoms.

Democracy, liberty, equality, and justice. These values are not very controversial. But Americans have vastly divergent viewpoints on the meanings of these core values. Does assisting the poor represent a movement toward equality, or does it create an unfair burden on the middle and upper classes? Does the permission of abortion defend the liberty of American women or endorse the ending of a human life? Do elected officials really represent the people, or are they just out for themselves? These issues and many more reflect a wide range of political attitudes that shape how Americans participate in government and politics.

Famous events from American history åÑ the movement West, the Civil War, the Industrial Revolution, involvement in World Wars I and II, the New Deal and the Great Society åÑ have been expressions of American political culture. Many events have questioned and answered various interpretations of American values and beliefs. But most of all, the political culture defines political attitudes, institutions, and activities that are most cherished in American political life.

Given the challenges of accurate polling of public opinion, it is amazing that polls that follow the right steps almost always make the right predictions. They've come a long way since George Gallup helped his mother-in-law win her election in 1932.

People may participate in politics in many ways. They can write their Representative or Senator, or work in for a candidate or political party. They can make presentations to their local school board or city council, or call the police to complain about the neighbor's dog. Partly because of our federalist system, people have many opportunities to participate in our democracy on federal, state, and local levels. Some forms of participation are more common than others and some citizens participate more than others, but almost everyone has a voice in government.

Voting is at the heart of democracy. A vote sends a direct message to the government about how a citizen wants to be governed. And yet, only 48.8 % of eligible voters actually cast their ballots in the 1996 presidential election. That figure represents the lowest general presidential election turnout since 1824. In off-year elections (those when the president is not running) the statistics are even worse. Why don't people vote?

Sure, state and local governments allow many opportunities to get in touch with government, but in some ways federalism just makes government all the more confusing and unapproachable. Yet a democracy depends for its very livelihood on meaningful contacts between the people and the government. How does this happen in modern America?

Elections form the foundation of the modern democracy, and more elections are scheduled every year in the United States than in any other country in the world. Campaigns åÑ where candidates launch efforts to convince voters to support them åÑ precede most elections. In recent years campaigns have become longer and more expensive, sparking a demand for campaign finance reform. No one questions the need for campaigns and elections, but many people believe that the government needs to set new regulations on how candidates and parties go about the process of getting elected to public office.

So, the election is over. How can the average American remain involved in politics without waiting for the next election? One chief means of influencing the American government is by joining an interest group — an organization that pressures elected officials to enact legislation favorable to its causes.

Despite promises made by presidential candidates, the President has no direct power to pass any legislation. This very important power lies solely with the House of Representatives and the Senate.

The Constitution specifically grants Congress its most important power — the authority to make laws. A bill, or proposed law, only becomes a law after both the House of Representatives and the Senate have approved it in the same form. The two houses share other powers, many of which are listed in Article I, Section 8. These include the power to declare war, coin money, raise an army and navy, regulate commerce, establish rules of immigration and naturalization, and establish the federal courts and their jurisdictions.

Partisanship — or fierce loyalty to one's political party — generally is not admired in the United States today. Many people today call themselves independent voters, and bickering between the parties in Congress is often condemned. But parties are very important in both the House of Representatives and the Senate today. Even though political parties do not play as big a role in elections as they once did, they still provide the basic organization of leadership in Congress.

Committees help to organize the most important work of Congress — considering, shaping, and passing laws to govern the nation. 8,000 or so bills go to committee annually. Fewer than 10% of those bills make it out for consideration on the floor.
