It is his body saying to him that this is his final term, and he shouldn't risk his remaining years running for yet another.
He should listen.
Yes he should listen to his body. There is more to life than being a Senator in Congress. Time to go fishing and golfing and relax in his very golden years.
That aside, my point is that he is benefiting from something that the Republicans are trying to deny to a large segment of society. And that's a shame.
And I might add that McCain's condition sounds very much like a "pre-existing condition".
