Appointed Senators (Present-1913)


The Seventeenth Amendment to the Constitution (1913) established direct election of senators, as well as a means of filling vacant Senate seats. If a vacancy occurs due to a senator's death, resignation, or expulsion, the Seventeenth Amendment allows state legislatures to empower the governor to appoint a replacement to complete the term or to hold office until a special election can take place. There are a few exceptions to this rule. Some states require a special election to fill a vacancy. A few states require the governor to appoint a replacement of the same political party as the previous incumbent. The date when a senator appointed to fill a vacancy is succeeded by a senator elected to fill the remainder of the term depends on a number of factors.

For more information on how vacancies are filled read, U.S. Senate Vacancies: Contemporary Developments and Perspectives (CRS) (pdf) and the Senate Document The Term of Senator: When Does It Begin and End? (pdf).

The names of current senators appear in bold print.

1. Wyman had run against John Durkin in the November 1974 general election for seat being vacated by Norris Cotton, but the election results were contested. In the meantime, Norris Cotton resigned his seat on Dec. 31, 1974, and the governor appointed Wyman to serve the last 3 days of Cotton's term. The seat was then vacant from Jan. 3, 1975, until Aug. 8, 1975, when Cotton was appointed to fill the vacancy pending the results of a special election to be held in September between Wyman and Durkin. Durkin handily won the special election.
