How this ranking is measured
U.S. senators ranked by their age on Election Day at the oldest election they won, so a long-serving senator is measured by his final winning campaign, not his first. Strom Thurmond, re-elected from South Carolina in 1996 at age 93, tops the list. Limited to popularly elected senators (1914–present) with a known birth date.
