## Introduction

Congress does not just make laws because the Constitution says it can. The way Congress is built strongly shapes which laws pass, which are delayed, and which never make it to a final vote. For AP Gov, this matters because exam questions often ask you to move beyond naming powers and explain how institutions actually work in practice.

The key idea is simple: the **structure** of Congress affects the **speed, content, and chances of success** of legislation. The House and Senate were designed differently, and those differences create different incentives, different rules, and different obstacles in the lawmaking process.

> **Key Term: bicameralism**
> The structure of Congress as a two-house legislature made up of the House of Representatives and the Senate.

### Bicameralism and why legislation is hard to pass

The first structural feature to know is bicameralism. A bill does not become law when one chamber likes it. It must pass both the House and the Senate in identical form, and only then can it go to the president. That creates an internal check inside the legislative branch.

This matters because the House and Senate are not duplicates. They represent different constituencies and operate under different rules. The House is based on population and is meant to be closer to the people. The Senate gives equal representation to states and was designed to be more stable and slower moving. Since both chambers must agree, legislation often changes as it moves through Congress.

For example, a proposal that is popular in urban House districts may face resistance in the Senate if senators from rural states think it hurts their statewide interests. Even if each chamber supports the same broad goal, they may prefer different details. One chamber may want stronger regulation, while the other wants more exceptions. Because the final bill must match exactly, bicameralism forces negotiation and compromise.

This is one reason Congress often seems slow. That slowness is not just dysfunction. It is partly built into the design. The framers wanted lawmaking to be difficult enough to prevent sudden, impulsive action.

> **Key Term: Origination Clause**
> Article I, Section 7, Clause 1 requires bills for raising revenue to begin in the House of Representatives, though the Senate may amend them.

The Origination Clause adds another structural difference. Revenue bills must start in the House, reinforcing the idea that taxation should begin in the chamber closest to the people. But the Senate can still amend those bills, so House control of origin does not mean House control of the final outcome.

> **Test Tip:** If an AP question asks how congressional structure affects policy, do not stop at “Congress has two houses.” Explain that both houses must pass the same bill, which creates extra veto points and forces compromise.

### Why the House and Senate behave differently

The House and Senate differ in size, term length, and constituency. These are not just background facts. They shape legislative behavior.

The House has **435 members**, each elected for **2-year terms** from relatively small districts. That means representatives face reelection often and usually pay close attention to district concerns. They are more likely to react to short-term public opinion, local industries, and constituency service pressures.

The Senate has **100 members**, with **2 senators per state**, each serving **6-year terms**. Senators represent entire states, so their constituencies are broader and often more varied. They usually have more time before facing voters again, which can make them somewhat less tied to immediate district pressure.

These differences help explain why the House often moves faster and the Senate more slowly. In the House, large membership makes loose debate impractical. Without strict rules, 435 members could delay almost any bill. So the House developed centralized procedures that let party leadership manage debate tightly.

In the Senate, the smaller size and longer terms encourage a more individualistic style. Senators generally have more opportunity to shape debate themselves. That gives minority voices more influence, but it also makes passing controversial legislation harder.

The two chambers also differ in their leadership structure. The **Speaker of the House** is a powerful presiding officer who can influence floor action and committee referrals. In the Senate, the vice president is the formal presiding officer, but real day-to-day power usually rests with the majority leader. This means House leadership is generally more centralized and forceful than Senate leadership.

> **Key Term: House Rules Committee**
> A powerful House committee that sets the terms of debate for bills, including how long debate lasts and whether amendments are allowed.

The Rules Committee is one of the best examples of House structure shaping legislation. Before many bills reach the House floor, the Rules Committee decides the conditions under which they will be debated.

An **open rule** allows members to offer amendments on the floor, subject to House rules. A **closed rule** blocks floor amendments. In practice, the House may also use more limited procedures that allow only certain amendments. This matters because amendment opportunities change both the content of the bill and the likelihood of passage.

If party leaders want to protect a carefully negotiated bill, they may prefer a closed rule. That prevents opponents from attaching hostile or embarrassing amendments. If leaders want broader participation or want members to feel heard, they may allow more amendments.

> **Key Term: open rule**
> A House rule that permits members to offer amendments to a bill during floor debate.
>
> **Key Term: closed rule**
> A House rule that generally prevents members from offering floor amendments to a bill.

The Rules Committee therefore acts as a gatekeeper. It can help move legislation quickly when the majority supports it, or it can delay a bill and make passage harder. In AP Gov terms, this shows that the House is more majoritarian and leadership-driven than the Senate.

Committees also matter before floor debate begins. Most bills are sent to **standing committees**, which are permanent committees with subject-matter jurisdiction. These committees hold hearings, gather information, revise bills in **markup**, and decide whether to send a bill forward.

> **Key Term: committee system**
> The structure Congress uses to divide legislative work among committees and subcommittees that review, amend, and oversee policy areas.
>
> **Key Term: standing committee**
> A permanent congressional committee with continuing jurisdiction over a policy area.
>
> **Key Term: markup**
> The process in which a congressional committee debates, revises, and amends a bill before deciding whether to report it.

Because most bills never leave committee, committee structure is a major reason legislation fails. A bill does not need to lose a dramatic floor vote to die. It can simply be ignored, delayed, or never scheduled.

In the House, the majority party’s control of committees and the Rules Committee means leadership has many ways to shape legislation before the full chamber even votes.

### Senate procedures: filibuster, cloture, and unanimous consent

The Senate’s structure creates a very different legislative environment. The most famous feature is the filibuster.

> **Key Term: filibuster**
> A Senate tactic used to delay or block action on a bill by extending debate or threatening extended debate.

The filibuster reflects the Senate’s tradition of less limited debate. In modern practice, senators often do not need to speak for hours continuously. The threat of a filibuster can be enough to slow or stop legislation. That means the Senate majority often needs more than a simple majority to move forward on controversial bills.

To end a filibuster, the Senate uses cloture.

> **Key Term: cloture**
> The Senate procedure used to end debate on most legislation, usually requiring 60 votes.

Cloture is important because it changes the practical math of lawmaking. Formally, a bill still passes with a simple majority. But if 60 votes are needed to end debate first, controversial legislation may fail even when more senators support it than oppose it.

This makes the Senate a chamber where minority parties and even individual senators can exercise major influence. That can protect minority viewpoints and encourage compromise. But it can also produce gridlock, especially during periods of polarization.

> **Key Term: unanimous consent**
> A Senate agreement to set terms for debate or quickly handle business as long as no senator objects.

Unanimous consent is almost the opposite of a filibuster. It allows the Senate to speed up routine business, but only when no senator objects. This again shows how much the Senate depends on cooperation. One senator can disrupt a unanimous consent request, just as a determined minority can complicate cloture.

It is also common for senators to attach **riders**, amendments that may be unrelated to the main bill. Because Senate amendment rules are less restrictive than House rules, senators have more individual opportunities to shape legislation.

> **Test Tip:** Students often confuse simple majority passage with the real difficulty of Senate action. In FRQs, explain that even if a bill can pass by majority vote, the filibuster means the Senate often needs 60 votes to end debate first.

When the House and Senate pass different versions of a bill, Congress needs another structural solution.

> **Key Term: conference committee**
> A temporary joint committee of House and Senate members that resolves differences between their versions of a bill.

Conference committees are temporary and formed to reconcile different chamber versions. Their compromise must then return to both chambers for approval. This means bicameralism can require not just two initial votes, but additional rounds of negotiation and voting too.

This final step shows why legislation is often fragmented and difficult. A bill may survive committee gatekeeping, win House approval, overcome Senate procedures, and still fail if the chambers cannot agree on one final text.
