This says more about the mainstream media than it does about youth - or about Jon Stewart:

America's twentysomethings, who are tuning into politics, trust Comedy Central fake-news king Jon Stewart more than network vets Peter Jennings and Dan Rather, a new study shows. Asked whom they trust more to inform them on politics, 17% said NBC's Tom Brokaw, followed by Stewart of "The Daily Show" at 16%. ABC's Jennings had 15% and CBS' Rather had 10%. And most people, 26%, picked "none of the above," according to the survey by Global Strategy Group and Luntz Research.

Presumably, they're not taken in by the myth that the problem with those anchors is "liberal bias" either...
