On a serious note, I think his VP pick is going to be critical.
Remember the melanoma removed from the left side of his face?
That side looks swollen to me.
There might be a health problem a short while down the road.
JMHO
Oh, I agree: Although most of any race is the Prez’ candidates’ merits, in THIS race McCain’s age makes his VP pick more important, more scrutinized. A bigger opportunity therefore to gain OR lose political ground, compared to most VP-pickings.
