Washington, D.C. — If Senator Chuck Grassley wins reelection, he could be in the line of presidential succession again. Since the World War II era, the longest-serving U.S. senator from the party that holds the majority of seats in the senate serves as Senate President Pro Tem. Grassley was in that role in 2019 and 2020 when Republicans held the senate majority.
Eighty-nine-year-old California Senator Dianne Feinstein is about three months older than Grassley. Feinstein has said she will NOT take on the role of Senate President Pro Tem if Democrats keep the majority in 2023.
