From a recent NY Times profile of McCain on the eve of the election..

“During the day he gets almost no exercise, eats the candy and junk food strewn all over his bus, and naps slumped in his seat in the curtained-off front section of his plane. The national reporters he once called his “base” remain banished in the back; aides say he is convinced that they are all rooting for Mr. Obama.”
I mean, root against him all you want, but he’s going to lose, and an old man who naps sitting up and spends all day eating junk food talking about how all the yung’uns are plotting against him, that’s just a little sad.
