 That president was Lyndon Johnson. Weakened by the Vietnam War, Johnson had never formally entered the race and bowed out five months before the convention. He was replaced on the ticket by his vice president, Hubert Humphrey, who won the Democratic nomination but lost the general election. Vice President Humphrey joined this broadcast a day before the start of the Democratic National Convention. President Johnson seems to believe that if he ran again, the country would remain divided and his move towards peace would be suspect.
