I don't know abut that Chris. I think Cain is smiling like that because he just gave the female producer of the shot a glance up and downThe ad would be rather boring if not for the end where is campaign manager takes a puff and then we see a satisfied smile from Cain as though he enjoyed seeing the guy smoke. It is just hilarious ad with no desirable message. It is almost as though they added the smoking bit to intentional cause a stir and it worked!
I for one am quite relieved to hear an official pronouncement that Obama no longer smokes.
