Why are two old, unpopular men the main candidates for the world’s most demanding job? It’s the question John Prideaux, The Economist’s US editor, gets asked the most. And the answer lies in the peculiar politics of the baby boomers.

Since 1992, every American president bar one has been a white man born in the 1940s. That run looks likely to span 36 years - not far off the age of the median American. This cohort was born with aces in their pockets. Their parents defeated Nazism and won the cold war. They hit the jobs market at an unmatched period of wealth creation. They have benefitted from giant leaps in technology, and in racial and gender equality. And yet, their last act in politics sees the two main parties accusing each other of wrecking American democracy. As the boomers near the end of their political journey, John Prideaux, The Economist’s US editor, sets out to make sense of their inheritance and their legacy.
