That could be the emotional toll. It's heartbreaking to see anyone - much less a relatively young mother - suffer with this. Maybe it was a trick of the camera angle, but it looked like she was standing five feet away from her husband. It was like she was an afterthought to Edwards' insistence that the campaign would continue.
You may be correct. Everyone knows she has a few rough months ahead and that may have hit her very hard.
I agree. He probably steamrollered over any opinions she might have had, which no doubt would have made her feel even worse than she already did. I see in her stance a defeated woman who has just been dealt the ultimate blow (the cancer returned) and has not been supported by the one who should be her protector and champion. She knows she is going to have to go through the worst alone and have to be strong for her children. I am so sorry for her. Money and power are no substitute for true love.
