2. How can both Sue and Sam be correct when Sue claims the commerce clause increases government's power and Sam claims the commerce clause reduces government's power?

When Sue claims the commerce clause increases government power she speaks of the federal government however when sam states that the commerce clause reduces government power he would be speaking of the state government.

Explanation:

The power of the federal government was expanded by the Commerce clause because it gave the federal government to regulate money and foreign trade. gives power to the states on everything not clearly given to the federal government.

the Commerce Clause as a restraint upon state exercises of power, absent congressional action, received no sustained justification or explanation; the clause, of course, empowers Congress, not the courts, to regulate commerce among the states.

The Commerce Clause does not give the federal government the power to abrogate the sovereign immunity of the states. Many described the Rehnquist Court's Commerce Clause cases as a doctrine of "New Federalism".
