I think Obama as a smoker is going to be a minor issue, regardless of what the pundits at Fox News say (didn't look like a slam piece to me, btw).
I think smoking shows a SERIOUS lack of personal judgement and self-control; expecially for someone as young as Obama. He KNOWS the health risks, and he knew them when he started, and he still does it. When he dies before his time, he is going to hurt people; its selfish.
Not to mention HIS side of the Aisle has many more people opposed to big tobacco than the other side.
Is the White House (West Wing) smoke free? Most government buildings are.
