Senior Senator

Seniority in the United States Senate is valuable as it confers a number of perquisites and is based on length of continuous service, with ties broken by a series of factors. Customarily, the terms "senior senator" and "junior senator" are used to distinguish the two senators representing a particular state.

Benefits of seniority

The United States Constitution does not mandate differences in rights or power, but Senate rules give more power to senators with more seniority. Generally, senior senators will have more power, especially within their own caucuses. In addition, by custom, senior senators from the president's party control federal patronage appointments in their states. Thus, being the junior senator may be disadvantageous if the senior senator is also from the same party.

There are several perquisites, including the following:

  • Senators are given preferential treatment in choosing committee assignments based on seniority. Seniority on a committee is based on length of time serving on that committee, which means a senator may rank above another in committee seniority but be more junior in the full Senate. Although the committee chairmanship is an elected position, it is traditionally given to the most senior senator of the majority party serving on the committee, and not already holding a conflicting position such as chairmanship of another committee. The ranking member of a committee (called the vice-chairman in some select committees) is elected in the same way.
  • Greater seniority enables a senator to choose a desk closer to the front of the Senate Chamber.
  • Senators with higher seniority may choose to move into better office space as those offices are vacated.
  • Seniority determines the ranking in the United States order of precedence although other factors, such as being a former President or First Lady, can place an individual higher in the order of precedence.

Determination of seniority

A senator's seniority is primarily determined by length of continuous service: a senator who has served for 12 years is more senior than one who has served for 10 years. Because several new senators usually join at the beginning of a new Congress, there are eight tiebreakers:[1]

  1. Former Senator
  2. Former Representative
  3. Former President of the United States
  4. Former Vice President of the United States
  5. Former Cabinet member
  6. Former state Governor
  7. Population of state based on the most recent census when the senator took office
  8. Alphabetical by last name (in case two senators came from the same state on the same day and have identical credentials)

When more than one senator has served in the same previous role, length of time in that prior office is used to break the tie. For instance, Barbara Mikulski, Richard Shelby, John McCain and Harry Reid all took office on January 3, 1987, and each had previously served in the House of Representatives. Mikulski, having served 10 years, is more senior than Shelby, who served 8. They are both more senior than McCain and Reid, who each served 4 years. McCain, however, outranks Reid because Arizona's population was higher than Nevada's as of the 1980 census.

Current seniority list

The president pro tempore of the Senate is traditionally the most senior member of the majority party. Only relevant factors are listed below. For senators whose seniority is based on their states' respective populations, the state population ranking is given as determined by the relevant United States Census.[2][3][4][5]
