Joe and Rob both mentioned this to me in the past week, and now several readers have brought it up. I also just noticed that Atrios picked up on this too today. Something wrong, changed, droopy or puffy with McCain's left eye. Anybody else notice anything? I just searched Google a bit more and found references to his eye being droopy in April and May of this year as well. But whatever it is, it seems to be intermittent. (McCain has had 4 bouts of melanoma, and did in 2002 have a benign growth removed from under his left eye.)
I decided to take a look at McCain's Herbert Hoover Speech, as Rob calls the economic speech McCain gave last Friday in Wisconsin, and tried to see what it was that Rob was noticing wrong with McCain's left eye. It was only a 15 second video, so I pulled it up in my iMovie movie editor and checked out each frame (see a selection of still shots above). What you see is apparently McCain's left eye more closed than this right, and/or when he blinks, his left eye is lazier, or blinks slightly out of phase with his right. Either way, it does look like something's up. Perhaps McCain has always had a bad left eye, though it's odd that so many people just noticed this week.
