Many people are criticizing Elizabeth Edwards for (a) standing by John Edwards and campaigning alongside him during his presidential bid, and (b) dragging this whole affair into the public eye again.
I admit that I don't entirely agree with those decisions either, but I think it's worth considering a couple other perspectives.
Regarding (a), we don't know that she knew the whole story during the campaign. She said all John told her was that he had a one-night stand with Rielle Hunter. And as devastated as she was by that, I think it's understandable why she, ultimately, agreed to go through with the campaign with that understanding. Telling someone to drop out of a presidential campaign because of a one-night stand one year before is a very different prospect from telling someone to drop a presidential bid because of an ongoing, year-long affair that may have resulted in a child and lots of hush money. If it really HAD been a one-time thing, it's plausible that it could have been kept a private issue between the two of them. The truth was quite different.
As for why she's replaying this whole thing in the public eye, you can debate whether it's best for her children or her marriage, but keep in mind that Elizabeth has ALWAYS been an extremely public person. She has grieved in public, shared intimate details about her life, and has always had a reputation for being a no-holds barred type of person. Witness this profile of her from a couple years ago:
Elizabeth has such an affinity for bloggers because, temperamentally, she is just like one.
For a political wife, she is unusually free with personal confessions. Since her husband ran for Senate in North Carolina in 1998, few of the family's most painful memories have remained sacred and private. We know that their son, Wade, died at 16 when a freak wind blew him off the road. We know that she had two more children, Emma Claire and Jack, at 48 and 50, respectively, after many IVF treatments. We know that she found a lump in her right breast in the shower, around the end of the last presidential campaign. We also know that she recently discovered her cancer had returned and spread to her bones when she and John were lying in bed; he put his head on her shoulder and "reached his arm over me to pull me close," she writes in her book, and then she winced and heard a pop--a fractured rib.
This stream of revelations has had an entirely different effect on both of their reputations. For Elizabeth, it's bolstered the voters' impressions that she is genuine, trustworthy, like a best girlfriend or even an Oprah figure, whose confessions of personal weakness only increase their admiration and awe. For John, it only seems to confirm suspicions that he is the slick trial lawyer adept at packaging pain and using it to his advantage. No matter how many times he puts on jeans and a work shirt, John Edwards can't shake his image as the "spoiled candidate who looks too good," as one middle-aged man confessed to Elizabeth at the house party in New Hampshire. The man later apologized to Elizabeth and explained that he'd only brought up the subject because he felt comfortable asking her anything. But this only raised the more important question: Is Elizabeth the perfect surrogate, or the person who makes it impossible to forget that her husband is the pretty one?

For her, this type of public grieving may be her way of dealing with it. And she may also feel that she can reach out to other women who have been in similar situations - cheating husbands, terminal illness, or, as is too often the case, both.
