Here’s another example of tiresome liberal bias on NPR. In a Kim Masters story on bias in the press on yesterday’s Morning Edition, there’s one soundbite of Gordon Liddy calling the media “flat-out Marxists,” and then a parade of liberals complaining about conservative bias: a producer with “The Daily Show,” the publisher of what Masters called the “left-leaning” Mother Jones, the creator of the new Fox-bashing documentary “Outfoxed,” and for faux balance, Ted Koppel, complaining that he beat Michael Moore to scoops. NPR even shows bias in its reports on bias.
