In American government's federal framework sovereignty (that is supreme and independent political authority) is what?

In the American federal framework, sovereignty is divided between the national and state governments, with each having its own areas of authority and responsibilities. The U.S. Constitution establishes the federal government as the supreme authority in matters explicitly delegated to it, while states retain sovereignty over local affairs. This division allows for a balance of power, ensuring that both levels of government can operate independently within their respective jurisdictions. Ultimately, sovereignty resides with the people, who grant authority to both the federal and state governments through the electoral process.
