Consider this debate between Ezra Klein and Mark Leibovich on “the real structure” of Washington, D.C.: is it the policy experts who understand how the country is governed, or is it the press secretaries and professional schmoozers who understand how to manipulate people inside and outside of the Beltway?
It's the basic contrast between Yes, Prime Minister and The Thick of It. The first is a world where the country is basically run by the civil servants. The second is the new modern world in which the country is run by the spinners and the manipulated press. The first is generally preferable, but neither is really the way things are supposed to be.
I'll also add that from my vantage point, the two groups aren't nearly as different as they probably think they are.
