Hmm. I always figured that FOX would be the least accurate. I don't think I've cited them for any reason. Ever. And if I wanted to, I always used another pollster to confirm their results.
Thats interesting to me because FoxNews did seem like the driver in what was the largest confirmation(in my mind at least) of the power of echo chambers to actually convince people that falsehoods are genuinely true in their minds. To the point where even those perpetuating the echo chamber falsehoods seemingly believed them to be true based on a reliance on underlying echo chamber information. A reliance on echo chamber falsehoods to make new perceived truths in the echo chamber. Creating this fascinating case study of being able to analyze biases on a national level.
What with many in the Romney camp, FoxNews, conservative media and their panel of conservative experts like Rove that genuinely thought Romney had a decent chance based on their collections of echo chamber "facts" that kept reinforcing themselves and pushing them further down the rabbit hole.
EDIT: Beaten, somewhat.
