The phrase "WE, THE PEOPLE" is of singular importance because it stipulates that the power and authority of the federal government of the United States of America does not come from the various states or the people of the various states, but from an entity that is identified as the People of the United States of America, with the Constitution serving as a compact or contract between the People of the United States of America, the various states, and the new entity: the federal government of the United States of America.
