This is a complete list of members of the United States Senate during the 86th United States Congress listed by seniority, from January 3, 1959, to January 3, 1961.
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]
In this congress, J. William Fulbright was the most senior junior senator and Edward L. Bartlett was the most junior senior senator at the start of the congress until Oren E. Long became the junior senior senator when Hawaii joined statehood on August 21, 1959.
Senators who were sworn in during the middle of the two-year congressional term (up until the last senator who was not sworn in early after winning the November 1960 election) are listed at the end of the list with no number.
