Perhaps, but she was in politics her whole life and was exposed to all the nasty goings on that happens. There is the draw of the office, of power and privilege many people put up with a cheating spouse in order to maintain their status quo.
There was that element there as well. She did want the lifestyle. She made a comment after he died that Camelot was no more, as if it were a loss to her. Also, I did read a biography many years ago that outlined her relationship with her Dad that you addressed earlier.
She did have a fabulous life, there is no doubt about it. She was beautiful, accomplished and had a vision when she revamped the WH. It was a different time back then though.
Yes it was, nevertheless, she brought a vitality and elegance which has survived through today.
In my opinion, it was a total fantasy that she was bringing to life. Do you think that Jackie was an intelligent woman? I mean in the brainy sense.
