Age apparently gives you wisdom, so why doesn't Joe Biden know when to quit? | Chris Mullin

Power is addictive - as certain world leaders insist on showing - but standing down from politics aged 62 was the smartest decision I ever made

Some years ago, at an African Union conference in Addis Ababa, I heard the then UN secretary general, Kofi Annan, say to an audience stuffed with life presidents: One of the tests of leadership is knowing when to leave the stage." All the big offenders were present - Robert Mugabe from Zimbabwe, Omar Bongo from Gabon, Teodoro Obiang from Equatorial Guinea and Yoweri Museveni from Uganda. They sat stony-faced amid much nervous foot-shuffling and laughter as the chairman, the former president of Mozambique, Joaquim Chissano (one of the few African leaders who stood down when his time was up), pointed at them and said, And we all know who Kofi was talking about, don't we?" It was an electric moment.

Annan may have been talking about African presidents, but today his words might equally apply elsewhere. Is it not extraordinary that, more than 200 years after it was founded, a political system as open and allegedly sophisticated as that in the US can only offer the American electorate a choice between two elderly males - one a serial liar and the other a decent man well past his sell-by date. One can understand what drives Donald Trump (77) - a desire to stay out of prison - but why on earth should Joe Biden (80), who has held elected office since 1972, want to cling to power? And not just Biden; what of Nancy Pelosi (83), until recently House speaker, or the Senate Republican leader, Mitch McConnell (81), both visibly fading? Or, indeed, the revered supreme court justice, Ruth Bader Ginsburg, whose refusal to recognise that her time was up arguably gifted control of the most important institution in the US to the hard right when she died in post in 2020 at the age of 87.
