Another Thought About Gannongate and the MSM

So why has the MSM mostly ignored Gannongate?
Most of the commentary I've seen on this -- courtesy of the blogosphere and Eric Boehlert -- has focused on either possible antsiness about linking the president to a gay prostitute or simple reluctance to be too hard on the president in the post-9/11 world.
I've got another theory: The MSM is simply embarrassed that it was too lazy to spot Gannon/Guckert sitting in their midst for almost two years. Not a single MSM reporter thought to question this person who came out of nowhere to appear among them with a "visitor" badge for all of this time, asking softball questions any time the going got anything close to tough for the White House.
Al Franken characterized the press as "lazy" in his recent book, Lies and the Lying Liars Who Tell Them. He was too kind. The MSM is lazy, corrupt, cowed, stupid, blind, etc., etc.
Thank goodness for the blogs. At least I can get information when I want it.
