From where does the authority of the government in the U.S. derive?

The authority of the government in the U.S. derives from the people. This principle is rooted in the idea of popular sovereignty, which means that the government's power is granted by the consent of the governed. The Constitution begins with the phrase "We the People," highlighting that governmental authority is established through the collective agreement and empowerment of its citizens. This concept reinforces the democratic foundation of the nation, where the government's legitimacy comes from the will and acceptance of its citizens, allowing them to participate in various forms of government, including voting and civic engagement.

While the Constitution serves as the framework for governance and outlines the structure of government and its limits, it is ultimately an instrument created by the people to serve their interests and uphold their rights. The role of the President and the courts is to operate within that framework set forth by the Constitution, but their powers are granted and limited by the authority that originates with the people.
