What does popular sovereignty have to do with the U.S. Constitution?

Answer 1

Popular sovereignty is reflected in the enumerated powers, and in the Ninth and Tenth Amendments. It is the basic principle of the American system of government; that the people are the only source of any and all American governmental power, that government must be conducted with the consent of the governed.

Basically, that the people being governed control the governing. Popular sovereignty indicates that the mandate of the people created government, and that political power comes from the people. However, in practice, political leaders abuse their power because they consider themselves sovereigns, instead of public servants. --- Popular sovereignty is the belief that the state is created by the mandate of its people, who are the source of all political power. It is closely associated to the social contract philosophers, among whom are Thomas Hobbes, john Locke and Jean-Jacques Rousseau.
