They count on the short memories of their viewers.
Media bias has been fairly transparent for a decade or two or three, but it's real easy to see now, and it (the media) has to fend off critics that it didn't have before.
They won't go down easy, and they aren't as powerful an influence over the public as they used to be.
Yep, exactly.
Luckily the media bias is so obvious now that even some people who I know who never believed there was bias -- are now wondering what's going on.
Then there are others I know, some even in my own family, who have gone off the deep end from listening to the constant Bush-bashing. It's getting pretty sad in one case I know about.
