With someone like Feinstein, I think the argument against them is that their age has reduced their ability to do their job effectively. Pelosi still seems pretty effective to me for what she tries to do. My issue with her is that she’s not very progressive. You could make an argument that that’s a function of age, but Bernie Sanders, who also seems effective but is for sure progressive, is 82.

I’ve never had a problem with someone doing any job at any age as long as they are effective. I manage a software engineering team, and my best, sharpest developer - the one most everyone goes to for help - is around 80. He loves what he does and my whole team is better with him on it. I’ve known other people who declined at a much earlier age.

So I hate setting an artificial age limit, but I wish we had some kind of test out performance measure that would force people out who can’t do the job.
