They came of age in the 1960s and ’70s, in the traumatic aftermath of the assassinations of John F. Kennedy and the Rev. Dr. Martin Luther King Jr. They fought and protested a war together, argued over Nixon and Kissinger together, laughed at Archie Bunker together. As children, they practiced air-raid drills; as adults, they cheered the fall of the Berlin Wall.

In the 1990s, they saw one of their own become president, watching him gain glory as one of the most gifted politicians of his time, but also infamy as one of its most self-indulgent — a poster child for the Me Generation.

They are of course the baby boomers, the collective offspring of the most fertile period in American history. At 75 million strong, they have been the most dominant force in American life for three decades, and one of its most maligned. Enlightened but self-centered, introspective but reckless, they are known among the cohorts that followed them — and even to some boomers themselves — as the generation that failed to live up to its lofty ideals, but still held fast to its sense of superiority.

If Bill Clinton was their white-haired id, Hillary Clinton is their superego in a pantsuit. A second Clinton presidency could represent a last hurrah for the baby boomers. But it could also offer a shot at a kind of generational redemption.
