Core concepts
Concept 1
Presidential power combines Article II authority, statutes, executive organisation, party leadership, persuasion and public leadership.
Exam cue: Identify whether a claimed power is formal, delegated, implied or informal.
Concept 2
Congress, courts, federalism, elections, bureaucracy, public opinion and events constrain presidential action.
Exam cue: Pair every example of presidential action with the relevant constraint or enabling condition.
Concept 3
Prime-ministerial and presidential leadership differ in selection, tenure, institutional fusion, party relations and legislative accountability.
Exam cue: Compare president and prime minister through a defined power or relationship.
