At the start of the fall general election campaign, Republican nominee and incumbent vice president Richard Nixon held a six-point lead in the polls. Major issues included how to get the economy moving again, Kennedy's Roman Catholicism, the Cuban Revolution, and whether the space and missile programs of the Soviet Union had surpassed those of the U.S. To address fears that his being Catholic would impact his decision-making, he famously told the Greater Houston Ministerial Association on September 12, 1960: "I am not the Catholic candidate for president. I am the Democratic Party candidate for president who also happens to be a Catholic. I do not speak for my Church on public matters—and the Church does not speak for me." Kennedy questioned rhetorically whether one-quarter of Americans were relegated to second-class citizenship just because they were Catholic, and once stated that "one asked me my religion [serving the Navy in the South Pacific". Despite Kennedy's efforts to quell anti-Catholic concerns and similar statements by high-profile Protestant figures, religious bigotry would dog the Democratic candidate through the end of the campaign. His score among white Protestants would ultimately be lower than Adlai Stevenson's in 1956, though Stevenson lost his election. Some Catholic leaders also expressed reservations about Kennedy, but the vast majority of laypeople rallied to him.
