Congress, along with the Presidency and the Courts, is one of the three vital branches of U.S. government, created so no single section or person would have supreme power. In theory, the Executive, Legislative (Congress), and Judicial branches serve as checks and balances to each other, preventing abuse of power. Naturally, since Congressional power is variable depending both on the other two branches and on its individual members, many people think that the Congressional system needs to be changed or altered. For example, many people think that there is too much influence from special interest groups, lobbyists, and political action committees (PACs), making objective legislation subject to financial sway. Most advocates for change agree that Congress is less likely to represent the people and more likely to vote and argue in favor of monetary influence. Others argue that Congress should be expanded in size, so that districts are not limited to one Congressional voter to 600,000 citizens. There are many arguments on both sides of the issue, but it is clear that the bureaucracy has become too expansive and too dependent on the views and desires of special interests and lobbyists. With more focus on the views and desires of the citizen voter, Congress would be better able to legislate based on their responsibility as representatives.
