There's a noticeable difference in Fox News coverage of poll numbers, compared to 2012.

This year, Fox News is much more likely to show how bad it is for Donald Trump. They are even showing Hillary Clinton winning the election (and Texas, yes Texas, as only a "lean" Republican) in their 2016 Electoral College map.

Part of the reason might be that Roger Ailes is no longer around to re-write the narrative for the network, but much more likely is how badly Fox News in particular got burnt after the election of 2012. Remember how much fun Jon Stewart had at their expense the day after?
