WASHINGTON (JTA) — Patrick Leahy, the Vermont Democrat who is the longest-serving member of his party in the U.S. Senate, announced on Monday that he will not run for reelection next year, setting the stage for Dianne Feinstein of California to be the first woman and first Jew to be the Senate’s president pro tempore, the third in line to the U.S. presidency.
The president pro tempore presides over the Senate when the vice president is absent, and also has the power to name people to administrative positions and commissions. The Senate elects the president pro tempore, which means that the position is always filled by a member of the majority party.
Since the mid-20th century, both parties have named their longest-serving senator to the job. Leahy has served in the chamber since 1975 and Feinstein has since 1992.
There is no guarantee that Feinstein, who was elected to serve until January 2025, will get the job. Republicans hope to regain the evenly divided Senate in next year’s midterm elections. Additionally, Feinstein, who is 88, is believed to be in ill health, and Democrats are not under any obligation to maintain the relatively recent tradition of nominating the longest-serving member of their caucus.
Should Feinstein assume the job, and should Democrats keep the U.S. House of Representatives in the midterms, there would be three California women lined up to succeed President Joe Biden should he leave office before the next election: In order, Vice President Kamala Harris, House Speaker Nancy Pelosi and Feinstein.
