John McCain once again had a growth removed and is having it biopsied.

Can John McCain keep the most basic of all promises - that he'll survive his first term? How about simply maintaining his health.

I think this is a real issue for the man and I think there is an outside chance that if he doesn't show that he can beat Obama by the convention, that he may be replaced because of health reasons.

If he remains the nominee, I think that this, together with the unending stream of memory lapses. will sink any hope he once had of becoming Pres.
