President Kennedy’s secretary Evelyn Lincoln wrote in her 1968 book Kennedy and Johnson that November 19, 1963 had been “one of the most pleasant days” she could remember in the White House. Kennedy’s schedule was light and he had spent long stretches of time in the rocking chair in her office, speaking pensively as he rocked.
“You know, if I am reelected in ’64,” he said. “I am going to spend more and more time making government service an honorable career,” adding, “I am going to advocate changing some of the outmoded rules and regulations in Congress, such as the seniority rule. To this I will need as a running mate in sixty-four a man who believes as I do.” As if thinking out loud, he continued, “. . . it is too early to make an announcement about another running mate—that will perhaps wait until the convention.”
“Who is your choice of a running mate?” Lincoln asked.
