"A media person would have never done this study," said Groseclose, a UCLA political science professor, whose research and teaching focuses on the U.S. Congress. "It takes a Congress scholar even to think of using ADA scores as a measure. And I don't think many media scholars would have considered comparing news stories to congressional speeches."
Of the 20 major media outlets studied, 18 scored left of center, with CBS' "Evening News," The New York Times and the Los Angeles Times ranking second, third and fourth most liberal behind the news pages of The Wall Street Journal.
Only Fox News' "Special Report With Brit Hume" and The Washington Times scored right of the average U.S. voter.
The most centrist outlet proved to be the "NewsHour With Jim Lehrer." CNN's "NewsNight With Aaron Brown" and ABC's "Good Morning America" were a close second and third.
