List of United States Senators in the 113th Congress by seniority


List of United States Senators in the 113th Congress by seniority

This is a classification of United States Senators by seniority from January 3, 2013 to January 3, 2015. It is a historical listing and will contain people who have not served the entire two-year Congress should anyone resign, die, or be expelled.

Order of service is based on the commencement of the senator's first term. Behind this is former service as a senator (only giving the senator seniority within his or her new incoming class), service as Vice President, a House member, a Cabinet secretary, or a governor of a state. The final factor is the population of the senator's state.[1][2][3][4][5]

Currently, Tom Harkin is the most senior junior senator (with Barbara Boxer the most senior senator junior to a member of the same party), and Elizabeth Warren is the most junior senior senator.

Notably, the current 113th Congress is the first Congress since the 103rd Congress (1993-95) in which no senator will have served for at least 40 years. The most senior senator, Patrick Leahy, will not reach the 40-year mark until January 3, 2015. From November 7, 1996, when Strom Thurmond reached the 40-year mark during the 104th Congress, until Daniel Inouye died on December 17, 2012, there was always at least one senator who had served for over 40 years.
