The Constitution establishes a government based on which principle that involves sharing power among different levels?

The principle that underlies the sharing of power among different levels of government is federalism. Federalism is a system where power is divided between a central authority and various regional or state governments. This design allows for multiple layers of governance, each with distinct responsibilities and powers.

In the context of the U.S. Constitution, federalism ensures that while there is a strong national government, individual states retain certain powers and rights, allowing them to address local issues effectively. This separation helps prevent the concentration of power in a single government entity and promotes a balance that can accommodate diverse needs across different regions.

The other principles, such as republicanism, democracy, and libertarianism, focus on aspects like representation, participation by citizens in governance, and the role of individual freedom. While they are all important concepts within the broader framework of governance, they do not specifically address the structure of power-sharing that characterizes federalism. Thus, identifying federalism as the correct principle highlights its crucial role in the organization of the U.S. government.
