You know, what they said about Mary Cheney is irrelevant--two wrongs don't make a right. This is not an appropriate angle of "attack".
No one wants to attack the children. The immediate issue here is the hypocrisy that allows John Kerry and John Edwards to attack Cheney's daughter, , and Liz Edwards to even suggest that the Cheneys are ashamed of her, and then to withhold their own situation from public scrutiny.
You may perceive this as an attack article, whether it was meant that way I can't say. But the hypocrisy issue is indeed valid if they want to lead this nation. And many people would indeed be concerned about the possible root issue of tossing fertilized human eggs away. That too is a worthy subject for the nation to consider. The only way to do that without mounting an attack would be to have an open and honest discussion, which isn't happening.
I also say God bless the children, no matter how they were conceived. But the more I learn about the Edwards the less I see to convince me they should be at the seat of power.
