The Structure of Leadership in Congress
The majority leader presents the official position of the party on issues and tries to keep party members loyal to that position, which is not always an easy task. In the event that a minority party wins a majority of the seats in a congressional election, its minority leader usually becomes the majority leader. The minority party in the House also has a leadership structure, topped by the minority floor leader. Whoever fills this elected position serves as the chief spokesperson and legislative strategist for the party and often works hard to win the support of moderate members of the opposition on particular votes. Although the minority leader has little formal power, it is an important job, especially because whoever holds it conventionally takes over the speakership if control of the House changes hands.
The Congress also has the power to impeach the president as seen in the case of presidents Nixon and Clinton (Smith, Jason and Ryan 120 – 191). The media and public opinion also prevent imperialism. The president should also have control and also listen to the counsel of family and friends. If these groups fail in any case, the Judiciary then takes up the matter and limit presidential powers to prevent imperialism.
Does this system encourage party loyalty above all else in members of Congress who want to get ahead? If that is the case, the impatience that Americans have with "partisan politics" is understandable.
