Gordon kept his jacket on to hide the fact that he appeared to be wearing a corset.
On the hospital visit and other times yesterday he wore a jacket, only in the evening (that I saw) did he conspicuously do the shirt sleeves. So I think your obsessing on this might be overdone. And who says Luntz is right? If he's the voice of God on these matters why has no party hired him for the campaign?
I thought the middle photo was Ed Balls for a moment. Scary.
