The last thing that the Founding Fathers envisioned was a hereditary chief executive. After all, they had fought a war in part to rid themselves of a king. Yet power inevitably passes from generation to generation, and several families have returned to the White House as though born to it. The stories of these four men profiled in this episode (John Quincy Adams, Benjamin Harrison, Franklin D. Roosevelt, John F. Kennedy) reveal both the blessings and the curses of inherited power. Two of them were ill-at-ease with their lofty legacies and struggled as president, while the remaining two flourished in the exercise of power.
