How is federalism related to popular sovereignty?

Federalism is a system of governance that divides power between a central authority and regional entities, allowing for multiple layers of government. This structure reflects the principle of popular sovereignty, wherein the ultimate authority rests with the people, who elect representatives at both the federal and state levels. By enabling local governance, federalism ensures that citizens have a greater say in political decisions that directly affect their lives, thereby enhancing the concept of popular sovereignty. Together, they promote a democratic framework where power is derived from the consent of the governed.
