According to Jefferson how should it be determined whether a power should be granted to the federal government?

According to Thomas Jefferson, the determination of whether a power should be granted to the federal government should be based on whether it is explicitly enumerated in the Constitution or necessary for the execution of its enumerated powers. He advocated for a strict interpretation of the Constitution, emphasizing that any power not explicitly granted to the federal government should remain with the states or the people. This reflects his belief in limiting federal authority to protect individual liberties and state sovereignty.
