In Chicago, the first televised debate takes place between presidential candidates Richard M. Nixon and John F. Kennedy.

During presidential election campaigns in the United States, it has become customary for the candidates to engage in one or more debates. The topics discussed in the debate are often the most controversial issues of the time, and arguably elections have been nearly decided by these debates. Candidate debates are not constitutionally mandated, but they are now considered an intrinsic part of the election process. The debates are targeted mainly at undecided voters; those who tend not to be partial to any political ideology or party.
