[F]or conservatives who have actually been in power, the liberal media thesis is a bit like the theory of intelligent design is for Rich Lowry and Peggy Noonan: an intellectual embarrassment. It's important to have those who passionately believe it as part of your coalition. They can do some serious damage to the opposition, so you want them "on" their game and active. But you can't operate with their press think. Like the social conservatives who deserve a seat on the bus but shouldn't be allowed to drive it, the yahoos who think the press is a tool of the Democratic party are needed but should not be heeded by conservatives in power.
