Shortly after noon on November 22, 1963, President John F. Kennedy was assassinated as he rode in a motorcade through Dealey Plaza in downtown Dallas, Texas.

By the fall of 1963, President John F. Kennedy and his political advisers were preparing for the next presidential campaign. Although he had not formally announced his candidacy, it was clear that President Kennedy was going to run and he seemed confident about his chances for re-election.

At the end of September, the president traveled west, speaking in nine different states in less than a week. The trip was meant to put a spotlight on natural resources and conservation efforts. But JFK also used it to sound out themes—such as education, national security, and world peace—for his run in 1964.
