Taftian theory

Taftian theory (also "Whig" theory)^[1] is a political term in the United States referring to a strict constructionist view regarding presidential power and the United States Constitution, where a president's power is limited to those powers specifically enumerated by the Constitution.^[2][3]

Taftian Theory was coined after the governing style of the 27th president of the United States, William Howard Taft. Most presidents prior to Franklin D Roosevelt subscribed to this theory, whereas more recent presidents (except Trump) subscribe to a stewardship theory.^[3][4]
