How true is that statement for second marriages, especially when one has very sizable assets that are brought to the marriage? I would expect that the rich partner might want to protect those from exploitation for whatever reason by his/her new spouse.
Also, isn't it true that Kerry just took a 6 million dollar loan on the mansion? If money paid on the mortgage was mostly hers, but both names were on the mortgage, that would be one way to get some campaign funds from her. However, after that I don't know.
