I forced myself to watch McCain on ABC's This Week with George Stephanopoulos.  McCain had his left side toward the camera, which was unusual since that is his "bad" side.

Moreover, his left eye was bloodshot and kept welling with tears almost to the point where a tear would fall.  Then the camera would cut away to George, and when the camera went back to McCain the eye would be dry, but still bloodshot.

Did anybody else notice this?  Is this just a case of pink eye, or is it possibly something more serious.  I know that there were concerns that his left eye was droopy a few days ago.  Is there an ophthalmologist who might give us a long range opinion?
