[Slogans] undermine whatever authority has been amassed by their speakers. There are a lot a of good things about CNN, John King being one. But the mechanical reiteration of a stupid catchphrase like "the best political team on television" calls into question the truth value and the earnestness of the whole enterprise. "Mildred, why are they saying that over and over again? Has Blitzer given the whole staff delayed echolalia?"
Seriously.
