Dear one they aren't. There are posters that seem to think that Mrs Edwards was "abused" when in fact she was as big a weasel as he is. The two of them deserved one another.
I think Elizabeth was a lesser weasel than her husband. Fighting cancer and trying desperately to stay beside her children for every remaining minute means she may have had to take a lot of his cr@p, including not telling the American people what scum he was, for fear he would take away her kids.
As a mom, I sympathize with her “trapped and dying” situation. She didn’t know how many months she would have to be with her kids, to give them as much of he as she was able.
She owed her kids every breath she had, and that is a higher priority for a mother than warning us — she probably figured that one day we would all find out what a loser this guy was, and she was right.
