Fox News is far more trusted than other TV news: The Public Religion Research Institute and The Brookings Institution poll

Via Erik Wemple's blog at the Washington Post with the title "Ouch: MSNBC barely registers in media study":

The failure of any outlet to reap a wider Democratic/liberal audience, suggests the report, could stem from ideological diversity within the Democratic Party (46% liberal, 31% moderate and 20% conservative). . . .

An alternative explanation is that there is relatively little difference between Broadcast News, CNN, and Public Television.  Possibly MSNBC's and the Daily Show with Jon Stewart's performances is so small because there are relatively few hard leftists.
