bilby commented on the word optics
"Shadow treasurer Joe Hockey, newly slim and ever-smiley, went to Parramatta Westfield on Tuesday. For most people this is called a walk, but for a politician it is known as a walk-through, a special species of perambulation that can only occur under certain conditions.
There must be cameras present to capture the spontaneous nature of the politician's interactions with locals. And he must be reasonably sure he will not be barged with a shopping trolley or gypsy-cursed by a passing pensioner - these things make for bad optics, as they say in the spin trade."
