What does the Whig theory of presidential power state?

The Whig theory of presidential power posits that the president's role is primarily limited to executing laws and carrying out the will of Congress, rather than taking an active role in policy-making. This perspective emphasizes a strict interpretation of the Constitution, suggesting that presidential powers are confined to those explicitly granted by the document. Consequently, the president should avoid overstepping authority and encroaching on legislative powers. This theory contrasts with the Stewardship theory, which advocates for a more expansive interpretation of presidential powers.
