What does the Constitution primarily do?

The Constitution primarily serves to set up the government and protect the rights of its citizens. It establishes the framework for the American political system, including the separation of powers among the legislative, executive, and judicial branches. This structure is essential for maintaining a system of checks and balances, ensuring that no one branch becomes too powerful.

In addition, the Constitution includes the Bill of Rights, which explicitly enumerates the fundamental rights and freedoms of individuals, safeguarding them from government infringement. This dual purpose of organizing government and safeguarding individual liberties is foundational to the functioning of democracy in the United States.

The other options do touch on aspects related to government and rights but do not encompass the broader scope of the Constitution's role. While the establishment of laws for the states, the definition of the court system's roles, and the rights of the states are important elements, they are not the primary focus of the Constitution itself. The essence of the Constitution lies in its foundational role in creating a government accountable to the people while ensuring the protection of their rights.
