I have been through this before. It was on my “Reliable Sources” program, in the fall of 2009, that the White House declared war on Fox News. Anita Dunn, then the White House communications director, called Fox “the communications arm of the Republican Party” and said, “It is not really a news network anymore.”

The resulting furor gave Fox months of fodder and was widely judged a tactical misstep that if anything elevated the network’s role.

There are times when many Fox programs, including in the nonopinion hours, appear to be on a jihad against the administration. And these days, MSNBC can be counted on to defend the Democrats almost around the clock.
