How this ranking is measured

Every sitting U.S. senator with a recorded birth date, ranked by age on September 9, 2026 (the day this page was last rebuilt, so the ages move only when the site does). "First elected" is the earliest election for this office that the person won, which is why a U.S. senator who first reached the office by appointment or succession shows a later year than the year they took the seat. 4 sitting members are not ranked: Ashley Moody (Florida), Jon Husted (Ohio), Alan Armstrong (Oklahoma), Darline Graham (South Carolina). Each reached the seat by appointment, succession, or a special election PolitiFinder does not yet hold, so there is no election record to build a profile from, and none of them would displace the leader above.
