BROOKE GLADSTONE: And now, for a few of your letters. My discussion last week with Frank Luntz on why so many believe weapons of mass destruction have actually been found in Iraq prompted Jim DeVries of Jennison, Missouri to say my liberal bias was showing. "This was clear from two things," he writes -- "her twice-repeated description with a faint note of disgust of Frank Luntz as a Republican pollster and her insistent attempts to get Mr. Luntz to admit that it was the Bush administration that had misled the public. No wonder the public doesn't trust the media. The bias is too obvious." But John Foker of River Falls, Wisconsin was, quote, "stunned and baffled" by my discussion with Luntz for the opposite reason. He says "How could a third of Americans believe that WMD have been found in Iraq? By listening to George W. Bush, for starters. In his chippy fashion, he turns on doubters and calls them 'revisionists of history.' Why," he asks, "do you continue to shield Bush and the administration? Why in the world would you ask a Republican pollster for an explanation?"
