Why would a 69 year old Grandmother admit she was a slut when she was 19 years old. That she had sex with a married man many times over.That she gave in to the Kennedy power and mystique.
I *think* the answer is Caroline (ya know) Kennedy is releasing taped interviews with her deceased mother. I think Jackie spills these beans in these interviews so the grandma is just getting out in front of the story.
One has to wonder if Jackie admits to her own affairs in these interviews.
