The Democrats' old-people problem

The elderly trend among Democrats:

A recent CNN poll found that five of the six people voters view as the leaders of the Dem Party average 71 years old (Sanders, Clinton, Schumer, Warren, Biden).

Four Democratic Reps. are more than twice the average age of their constituents: Rep. John Conyers (Mich.), 88; Rep. Eddie Bernice Johnson (Texas), 81; Rep. Lucille Roybal-Allard (Calif.), 76; Rep. Jose Serrano (N.Y.), 74.

A few senators running for re-election will be in their 80s after another six years in office: Feinstein, Sanders, and Sen. Bill Nelson, 75.
