Chyna will likely get in the HoF one day, when Paul and Stephanie have finally become mature adults outside of Vince's influence. Remember that Vince enabled the relationship and punished Chyna for it, so he really has the most to gain from Chyna's fall and to lose from her redemption.
I understand how infidelity and then ostracization from someone you really loved can damage a person. Chyna made some bad choices from her hurt, and even recent interviews, talking of Paul's alleged abuse (which she tolerated in the r/s she still wanted), shows she's still not over it.
Still, Chyna's accomplishments are unassailable. She will be given her due, once more of the scabs heal. Sunny is already in the HoF (New Jack was right about how he got in, as Terri relayed to him) and can only go down from this point, which she is daring the WWE to let her do.
We all know this poll's answer, and it's good to see Chyna start getting the respect she deserves.
