I don't think the Kerry's marriage is anything like the Clinton's and certainly not a business arrangement. Or at least Mrs. Heinz didn't plan for it to become that way. I think she is a romantic who was in love with her first husband and tried to replicate it with another senator. He, OTOH, just wanted her money. She was sharp enough to force him to sign a prenup, but is only now seeing the degree which her money was a factor in their marriage. She doesn't have the political aspirations Hill has. She wants to be left alone to distribute her millions in her foundations... This campaign is getting in her way and it's showing her what she really married...
Statistics show that widows and widowers who had a happy first marriage, will usually remarry within a short time of their partner's demise. Those same statistics show that individuals who had a bad or unhappy first marriage will not remarry, or will be very slow to do so again.
I would certainly agree with much of what you said. You have to admit though.... they are light years from the relationship that George and Laura have.
I think you're right. She doesn't need this, she has the loot to buy her privacy and is maybe realising she will lose this privacy and her independence if (hopefully a gigantic if) he wins. Couple that with the pressure and stress of campaign travel, rallies etc, it must be a horrible shock and who could blame her for wanting to say the hell with it, I want to go home !
