8 Oldest Members of Current U.S. Senate

  1. Chuck Grassley (R-IA): 92
  2. Bernie Sanders (I-VT): 84
  3. Mitch McConnell (R-KY): 83
  4. Jim Risch (R-ID): 82
  5. Angus King (I-ME): 81
  6. Dick Durbin (D-IL): 80
  7. Richard Blumenthal (D-CT): 79
  8. Ed Markey (D-MA): 79

Notably, KY and VT have Governors of the opposing party, so if either McConnell or Sanders were to pass away in office, they’d likely be replaced by someone from the opposing party until the next election.

McConnell won’t run again in 2026, but Bernie just won reelection and would turn 90 a month after he leaves office in 2031.
