We expect anchormen and -women to have sort of "plastic" hair, and to look perfect. In fact, I suspect we subconsciously desire it. (Would you watch a newscast with a slovenly-looking anchor?)
But if a candidate is said to have "anchorman" hair, that's bad.
Interesting. Perhaps it's because we expect TV newscasters to look a bit fake--after all, they're for show. But we hunger for authenticity from our politicians.
