Predictably there is a lot of political polarization in which outlets people trust. 74% of Republicans trust Fox News, but no more than 23% trust any of the other four sources. We already knew that conservatives don't trust the mainstream media but this data is a good prism into just how deep that distrust runs.

For Democrats the numbers are a complete opposite- a majority trust all of ABC, CBS, CNN, and NBC while only 30% have faith in Fox News. Continuing the trend in our polling over the last few months that independents hate everything, a plurality of them distrust all five outlets we looked at.
