John Ziegler is known for making waves on talk radio. Now he's started a tsunami with his forthcoming documentary "Media Malpractice … How Obama Got Elected." In November, Ziegler debuted excerpts from the film, which examines how news media impacted the 2008 presidential election, on Fox News' "Hannity & Colmes." The purpose of the video, said Ziegler, was to determine "the impact of the news media on what Obama voters knew -- or thought they knew -- about the campaign."
