    “This country has come to feel the same when Congress is in session as when the baby gets hold of a hammer.”

    –Will Rogers (1)


    Being a senator or representative is a complicated job and involves several roles. Of course, its primary function is legislative (law writing).

    • Substantive laws are those that make a change in federal law or that authorize spending taxpayer dollars.
    • Ceremonial laws are those that do relatively trivial things like rename federal buildings, award medals, or designate special days.

    In the past twenty years, Congress has passed between 200-450 substantive laws per session and between 50 and 250 ceremonial laws per session. (2) Sitting congressmen run for reelection based on their legislative records: What “good” bills did they push, and what “bad” bills did they oppose? They campaign on their legislative abilities, and local media report on the status of a candidate’s important legislation. The theory of representative democracy rests on the rather large assumption that voters assess legislation and reward those politicians who have voted “correctly” on the issues that matter to voters.


    Representation is closely related to the legislative role. Congressmen are elected to represent their constituents’ interests. Elections often do not convey the voters’ wishes clearly to the politician. If a politician wins with 53 percent of the vote, she cannot be certain from those results of what the voters want her to do. As a result, politicians are fond of polls and focus groups conducted by survey-research organizations. In addition, congressmen can access other information sources by reading local newspapers, conversing with lobbyists, talking to elites in the district, and soliciting constituent views during town meetings. Also, the representative’s role is to decide what kind of representation is best.

    • Should the politician be a delegate, who is bound to vote the way constituents want?
    • Should the politician be a trustee, a representative who is directed by his or her own judgment rather than their constituents’ views?

    In Federalist #10, James Madison wrote that representatives “may best discern the true interest of their country,” and that their “patriotism and love of justice will be least likely to sacrifice it to temporary or partial considerations.” What do you think? Should a member of Congress be a delegate or a trustee? Who is more likely to assume the delegate roll—representatives or senators?

    Constituent Service

    Another important congressional role is to perform constituent service, which is often referred to as casework. Are your veteran’s benefits caught up in red tape? Did you fail to receive the cost-of-living adjustment in your social security check? Did your community theater federal grant application get lost? Call your senator or representative’s office—staff people are there to help you if they can.

    Constituent service is a way for a congressman to garner good favor and positive news coverage in their district. Also, casework can serve to educate congressmen, particularly with respect to legislation and oversight. As one Congressmen put it: “You learn more about the job by doing constituent service work than anything else. . .It tells you whether or not the legislation is doing what it is supposed to do.” (3) Constituent service can also become controversial, especially when politicians are seen to be doing the bidding of well-heeled citizens or corporations, both of whom donate money to congressional campaigns and seem to have better access to congressmen than do ordinary citizens.


    A final important congressional role is performing executive-agency oversight. Congress is interested to see how programs and regulations are actually working and what impacts federal laws have once they go into effect. So, standing committees and their subcommittees hold hearings to inquire into those executive agencies’ operations. Congressmen sometimes have an interest in exposing waste, fraud, and abuse in the executive branch. Often, those agencies’ heads are called to testify before a committee or subcommittee, and experts from the General Accounting Office—which is the investigative arm of Congress—testify about their investigations.

    Presidents from both parties as well as the intelligence agencies have resisted Congress’ efforts to get the information it needs. With respect to presidents and other executive officials, there is a clear tension surrounding executive privilege. Although executive privilege is never explicitly mentioned in the constitution, presidents have long held that they are entitled to withhold from Congress certain executive branch documents and deliberation transcripts within executive agencies. They also contend that executive privilege allows them to defy congressional subpoenas to testify before oversight committees. We’ll talk more about executive privilege when we get to the presidency section of the text.
