Baby Boomers Dominate the Chamber
The Baby Boomer generation, born between 1946 and 1964, forms the backbone of the Senate GOP. More than half of Republican senators fall within this age range. The group includes lawmakers such as Lindsey Graham (70), John Thune (64), and Marsha Blackburn (73).
The Silent Generation Still Holds Sway
A few members of the Silent Generation continue to wield significant influence. Chuck Grassley (92) has served in the Senate since 1981 and is currently its oldest member.
