That's quite some smirk on Mitt Romney's face as he walks away from the podium in Jacksonville, Florida, having just woven in criticism of Barack Obama to his reaction to the murders in Benghazi. The photograph was taken by Charles Dharapak of the Associated Press, and I suspect it's going to be one of the most significant images of the campaign. Maybe Mr Romney was just unlucky, but on the other hand… are you surprised? Honestly?
