Because Watergate tested the strength of the U.S. constitutional system and proved that it worked, this unit could serve as a focal point for study of the U.S. Constitution. The three objectives of the document are: (1) to expand knowledge of the governance process through study of the separation of powers, the impeachment process, the right to privacy, and the electoral process; (2) to develop skills that promote critical thinking and analysis of issues by using reference sources; and (3) to develop attitudes congruent with citizen participation in a democratic society by affirming belief in the ideals of U.S. democracy and in the democratic process as a way of achieving those ideals. The first theme, "Presidential Power in the United States," presents events that culminated in the "imperial presidency," and the resulting corrupt practices in trying to gain and hold that position. The second theme, "Curbing the Powers of the President," discusses the constitutional limitations of presidential power. The third theme, "Political Morality," delves into the political practices that made Watergate possible. Activities and questions to enhance the discussions are included, and a bibliography is appended. (SM)
