What I would do, were I John Edwards, is a different path that he and his wife have chosen to take. I think it is great that she is so supportive of his goals, but they have very young children, plus the campaigning, let alone the role of the First Lady is very, very taxing.
I am going to keep her in my prayers, and hope that she can hold up to the pressure that is going to be heaped on her and her family.
