This book explores how and why Vietnam loomed so large for Humphrey as vice president from 1964 through the 1968 election campaign against Richard Nixon. It assesses how Humphrey’s loyalty to Lyndon B. Johnson, who emerges as the villain of the story in many ways, would negatively affect his political ambitions. And it engages the disconnect between Humphrey’s principles and the intricate politics of his convoluted relationship with the president and his unsuccessful presidential campaign. It is a complex and frustrating narrative, the results of which would be tragic, not only for Humphrey’s presidential aspirations, but also for the war in Southeast Asia and the future of the United States.
