How did you get "better" out of "not entirely bad news"???

Extremists and hard core partisans are going to remain that way.  They're the ones consuming most of the extreme fake news.  

It's the people that don't have their minds dead set on one extreme or the other (or just tend to be disinterested in general) that are more pliable.  Subtle bias is often worse for manipulating those people because they're more open to it and don't realize they're being manipulated as compared to a source that's pushing obvious bias. 

Most everyone else already has their mind made up.
