Jonathan S. Tobin of Commentary agrees with some of the key findings of a Politico story detailing the president’s “mastery of the mainstream media.” Unlike the Politico scribes, though, Tobin focuses some attention in his latest column on the liberal bias infecting members of the media themselves.

No matter how smart the strategies employed by the White House, the president’s ability to skate through four years without getting seriously challenged by the mainstream media would not have been possible if most of those being played were not willing accomplices. Due credit must be given to the administration’s ability to take advantage of technology as well as their brilliant if unscrupulous game playing with journalists. But without the liberal bias of most of the mainstream outlets that let the president play them like a piano, he would come across as a bully and a demagogue rather than the reasonable nice guy seen in those “60 Minutes” interviews he loves to give.

Any analysis of the president’s media advantage must start with the understanding that his historical status as the first African-American president has given him far more leeway than any of his recent predecessors when it comes to scrutiny from the mainstream press. The broadcast networks as well as the liberal-leaning cable channels have treated Obama and his family as being above criticism. This has created a Camelot effect unseen in Washington since the days when the press was ignoring JFK’s personal immorality while turning his family into national icons.

The White House has ruthlessly exploited that willingness to portray the president in the sort of stained-glass light usually reserved for statesman of the past. But, as Politico rightly points out, they have doubled down on it by limiting access to the working press — even those from generally friendly liberal outlets — and going directly to the public via social media and White House-created content. That has been combined with cleverly staged leaks to journalists who then dutifully do the administration’s dirty work for it on a host of issues. All this allows the president to pose as the voice of reason on domestic issues and to generally avoid any pointed scrutiny on foreign affairs even when — as in the Benghazi fiasco — the duty of the press to focus on his lack of answers would seem obvious.

Politico is right that among those most frustrated by this are members of the White House press corps who may be liberals but are still eager to do their jobs. However, the only reason this has worked so well is the willingness of the editors and publishers who employ those frustrated reporters to roll over and play dead for the president. The unavoidable fact that Vandehei and Allen do their best to ignore is that the hamstringing of the working press’s ability to hold the president accountable dovetails nicely with the editorial stands of the vast majority of those outlets.
