We criticize MSNBC enough for its naked advocacy on behalf of the Democrats and Barack Obama, so in all fairness, we should note that they do have limits … and Alan Grayson apparently found them. Contessa Brewer engages Grayson on his disgraceful, dishonest “Taliban Dan” smear and — to her credit — refuses to let him off the hook for it. At one point, Grayson accuses Brewer of distracting attention from women’s issues, but Brewer fires back and tells Grayson that he approved the ad and its own off-message smears and out-of-context quotes. If Grayson was serious about the issues, Brewer asks, why not just stick to the issues rather than issue an ad rated “false” by Factcheck?Finally, MSNBC does some constructive, critical criticism of a far-Left loon. Maybe more of this might help boost their abysmal ratings.
