United States Senate
The United States Senate is the upper chamber of Congress. Often called “the world's greatest deliberative body,” the Senate is designed to give each state equal representation regardless of population.
Composition
Equal Representation
Each state has exactly 2 Senators, regardless of population. This means Wyoming (population ~580,000) has the same Senate representation as California (population ~39 million).
Total Membership
100 Senators total: 2 from each of the 50 states. This number has remained constant since Hawaii became the 50th state in 1959.
Leadership
President of the Senate
The Vice President of the United States serves as President of the Senate but may only vote to break a tie. In practice, the Vice President rarely presides over daily sessions.
President Pro Tempore
The Senator who presides in the Vice President's absence. By tradition, this position goes to the most senior member of the majority party. The President Pro Tempore is third in the presidential line of succession.
Majority and Minority Leaders
The Majority Leader is the most powerful Senator, controlling the floor schedule and legislative agenda. The Minority Leader represents the opposition party. Both are elected by their respective party caucuses.
Requirements and Terms
Qualifications
- At least 30 years old
- U.S. citizen for at least 9 years
- Resident of the state represented
Term of Office
6 years, with no limit on the number of terms. Elections are staggered so that approximately one-third of Senators are up for election every two years (Class I, II, or III).
Exclusive Powers
The Constitution grants certain powers exclusively to the Senate:
- Advice and Consent: The Senate must confirm presidential appointments to the Cabinet, federal judiciary (including Supreme Court justices), ambassadors, and other key positions.
- Treaty Ratification: Treaties negotiated by the President require approval by a two-thirds vote of the Senate.
- Impeachment Trials: When the House impeaches a federal official, the Senate conducts the trial. A two-thirds vote is required for conviction and removal from office.
The Filibuster
Unlike the House, the Senate allows unlimited debate unless 60 Senators vote for “cloture” to end discussion. This means a determined minority of 41 Senators can block most legislation through a filibuster.
The 60-vote threshold effectively requires bipartisan cooperation for major legislation, making the Senate a more deliberative and slower-moving body than the House.
