Researchers studying succession in family businesses turn their lens on Congress, where eleven octogenarians won primaries for the 2026 midterms, led by 83-year-old Sen. Jim Risch. Sen. Ed Markey, 80, beat a 47-year-old generational-change challenger by nearly 30 points, while the House and Senate medians sit around 60 and 66 respectively.
The piece contrasts Barbara Boxer, who announced her exit in 2015 at 74 and let successors organize for nearly two years, against Dianne Feinstein, who stayed through a lengthy 2023 health absence and died in office at 90 while her seat on the Judiciary Committee sat deadlocked. Kay Granger didn't cast a vote in her final six months before dying at 83 with dementia, and Mitch McConnell, 84, plans to finish his term despite a 2026 fall and hospitalization.
Biden's late withdrawal and Harris's nomination without a single primary round out the piece as the marquee case of succession arriving under duress rather than by design.
