On Vox Populi today, Vox made the claim:
[T]he situation [...] has existed on the Left for decades. They believe literally everything the mainstream media reports, despite the fact that what is generally known as “the news” is a false narrative that has little more than an incidental relationship with the objective truth of what actually happened.
I found this to be an exaggeration (for the sake of explanation, as they say in Danish). But no, apparently not. The pollster Frank Lutz claims (today, just now), seriously and without qualifications, that “Two thirds of Democrats believe #FakeNews“.
