Thus a more inclusive definition of Nixonland: it is the America where two separate and irreconcilable sets of apocalyptic fears coexist in the minds of two separate and irreconcilable groups of Americans. The first group, enemies of Richard Nixon, are the spiritual heirs of Stevenson and Galbraith. They take it as an axiom that if Richard Nixon and the values associated with him triumph, America itself might end. The second group are the people who wrote those telegrams begging Dwight D. Eisenhower to keep their hero on the 1952 Republican ticket. They believe, as did Nixon, that if the enemies of Richard Nixon triumph — the Alger Hisses and Helen Gahagan Douglases, the Herblocks and hippies, the George McGoverns and all the rest — America might end. The DNC was right: an amazingly large segment of the population disliked and mistrusted Richard Nixon instinctively. What they did not acknowledge was that an amazingly large segment of the population also trusted him as their savior. “Nixonland” is what happens when these two groups try to occupy a country together. By the end of the 1960s, Nixonland came to encompass the entire political culture of the United States. It would define it, in fact, for the next fifty years.
