As far as his physical health, I could care less if the guy could type.
I do however, wonder why the left side of his face(HIS left side, right side in pictures) seems to have a bulge that gets larger, by his jawbone. McCain, being a cancer survivor 3x (4x??) now, that particular area is a hotbed for regrowth due to the amount of vascularization particular to the area. Prior to election day, I would very much like to see him get a complete update of his physical, which we all know won't happen anyway, or, better said, won't be released in entirety. The other night at the "Service" forum, it seemed the whole side of his face had started to swell, and it was the worst I had seen it...two other people watching the debate with me made comments on it.
I have serious questions on whether he is free of metastatic cells.

Older pic, but you can see a difference from one side to the other.
