One clear merit to the political condition of Presidential Imperialism is that, it allows the office of the president to carry out the responsibility to conduct ongoing wars and ongoing foreign relations, and to respond to sudden attacks if Congress were not in session.

One clear demerit of the idea of Presidential Imperialism is the potential to abuse power.
