It boils down to which of these options do you think is most likely:
1. Edwards said he would take a DNA test because he has already taken one and knows he is not the father; or
2. Edwards said he would take a DNA test because he knew Hunter would refuse to take one and Edwards is willing TO BET EVERYTHING on Hunter not changing her mind.
Keep in mind, if Edwards is the father, Hunter will be able to get a healthy percentage of Edwards' income for the next 18 years as child support, sell her story and exclusive pictures to a tabloid for a minimum of $1,000,000, and then sign a book deal and go on the talk show circuit. In addition, if Edwards is the father and Hunter is refusing to allow a DNA test because he asked her not to, then she can blackmail him for any amount she wants.
I just don't think there is any possibility that they haven't both had DNA tests run, probably without the knowledge or consent of the other. It was just too easy for each of them to acquire the necessary DNA samples and too stupid for either of them to make any demands, speak to the press, or refuse to speak to the press without knowing for sure the paternity of the baby.
“2. Edwards said he would take a DNA test because he knew Hunter would refuse to take one and Edwards is willing TO BET EVERYTHING on Hunter not changing her mind.”
I believe that Hunter loves Edwards and that most likely Edwards promised her they would be together after Elizabeth dies. She will most likely try to cover for him as long as she can so she will continue receiving financial help.
If, as you say, Edwards knows he is NOT the father of Hunter’s baby, why has he met with her three times in the last month or so according to the National Enquirer? Obviously the affair was not “ended in 2006” as Edwards AND Elizabeth have said.
