This comparison of viewers aligned with the broadcast networks, CNN, MSNBC, and Fox reveals striking differences in reaction to questions regarding Trump and the Mueller probe. The responses clearly show that the opinions of Fox viewers are much different than the opinions of those who primarily get their news from one of the other sources.
The interesting question is whether viewers select an outlet consistent with their beliefs or whether beliefs are associated with content differences across outlets. However the relationship works, Fox viewers are clearly distinct.
One of the pollsters compared the situation to a hung jury in which one jurist prevents a conclusion. Of course the analysis of news access does not offer totals across what appear to be two camps, but it does appear that Trump’s claim of “fake news” is focused on a diverse set of outlets rather than a distinct target. The distinct outlier in this case is Fox.
