Pay no attention to the man behind the shrubbery

I found this image on Atrios' site. I'm not sure what to make of it, did Dick Cheney not realize he was in the shot?

You could write a whole novel about this image. There's Bush at the podium, trying to salvage the last shreds of his presidency, while over there in the middle distance, Cheney looks on.

What is that look? Is it the envy of the balding, heart-disease-riddled man with the permanent sneer who knows how unelectable he is?
