I never heard that. Too bad Kennedy had to win it with slimy humor.
I’m not sure how you consider Kennedy saying that it was Ms. Truman’s problem was “slimy” humor. On the other hand given the noble sounding boasting about the high moral tone that he, Nixon, would bring to the office, I found it quite shocking to hear the language he taped when he was talking in private with his staff. I don’t know if you were an adult at that time, but a lot of people were pretty shocked by i at the time.
