The phrase “We the People” introduces the United States Constitution. The purpose of these words is to establish that the American government system is led by its citizens. Citizens have the power to decide how the country will operate. This is known as popular sovereignty, which is one of the foundations of American government. The government does not get its power from a king or Congress, it receives all of its power from the people it serves. The concept of popular sovereignty is reflected in the United States today because people have the right to vote. They can elect representatives and the president. If they are unhappy with elected officials, they have the right to replace them. Citizens also have the right to protest against their government without the fear of suppression or oppression from higher authorities.
