In this contributed volume, authors examine the different approaches that drive the current debate concerning the presidency: liberal, conservative, moderate, constitutionalist, libertarian, and presidentialist (unitary executive). All chapters follow a consistent structure, encouraging students to compare ideas across chapters. Contributors also examine their approach in light of presidential-congressional relations, presidential power and accountability, the rule of law, as well as domestic and foreign policy. Making explicit what is often implicit, this engaging and unique examination of the presidency helps readers better understand presidential power and leadership.
