Well, every once in a while CBS breaks ranks and reports breif versions of real news
I am not sure if their viewers are independent/moderates+ libs or what, but it doesn't seem to effect them. People with liberal tendencies (and some cons too, I won't lie), will always assume that everything negative that happens is COMPLETELY the other sides fault.
Economy is Bushes fault, and now house republicans for not raising the debt ceiling.
Fast and Furious was Bushes fault too (even though his similar plan was called something else, and Bush stopped it before it really got starte,d, realizing the danger).
Benghazi was House republicans fault, for reducing spending to our embassies. It was also the fault of a video
Housing crisis is Bushes fault
We are still at war because Bush started it and the pubs are warmongerers.
Etc...etc...etc. I think people would just assume the alphabet networks had "gone conservative" and they wouldn't pay attention. No way would all those people admit they were wrong.
