Your media team has been so focused on the primaries that this blog hasn't been getting its usual love. This picture doesn't meet my usual criteria for a strong news picture, but it stopped me in my tracks nevertheless. Politicians and their handlers are so careful to manage their public image that we hardly ever see them in an unguarded moment. This image of presidential candidate Mike Huckabee speaks volumes about the stress of the campaign trail: the slumped shoulders, the downcast expression and the shopping bag. It reminds me of the work of photographer Robert Frank in the 1950s.
