While I agree with much of what you have said, think about American society at the time and from a historical perspective. Post WWII Eisenhower, a grandfatherly figure, was a remnant of a grateful America who rewarded him with two terms. Kennedy was the optimistic transition kid with the glamorous wife.
Kennedy was on the leading edge of a societal revolution. He was young, good looking. He had a hot wife and he was a known philanderer. Think of what came directly out of this. I'll give you a hint, Hugh Hefner.
Right at this exact moment the whole Playboy persona exploded in American culture. In large measure because American society wanted to emulate the young, suave, powerful guy who sexually attracted all the girls. That was the Kennedy persona, or myth, constructed or not. This is exactly why Hugh Hefner was exactly in the right place at the exact right historical moment. At that time every guy, and I mean every one, fancied himself a Kennedy-esque Playboy.
What else happened culturally that was Kennedy-esque? In 1963 the first James Bond movie was released (Dr. No). Again, the handsome, powerful guy who possessed all the sexual prowess to score any woman.
It's hard to underestimate the deep cultural impact of the sociology at the time that Kennedy had. It was like, after the abject hardships and suffering of WWII America had turned a page. We were becoming very economically powerful and youth and optimism were surging, and Kennedy was that transcendent and iconic symbol of that historical moment.
>>Kennedy was on the leading edge of a societal revolution.
Fascinating connection that I never made.
