PBS Covers for Obama, Edits Transcript

And by "cover" I mean edit his historical gaffes so no one (and by no one I mean the historically ignorant) can claim that the "brilliant" Obama is wrong or doesn't know his history. Well, from the MSM's attack on Sarah Palin's correct assessment of Paul Revere to her "attacking" Democrats on a political district map we know how much the media knows of history. We also know the limits of the president's knowledge of his own history as he apparently didn't know he was born four years before his parents met "on that bridge in Selma."

But to what lengths did PBS go to cover for Obama? Well, how far is omitting parts of a transcript to protect his lack of knowledge?

I know the media will never admit that Obama isn't as smart as they claim he is, or that they'll never collectively admit he's a failure as president; but can't they at least admit when he's wrong? Even once? Just a little bit?
