I watch MSNBC at home, and FOX news at the gym (weights and cardio), so I see a lot of both.
Whenever FOX does a news piece, they always label the democrat. But not republicans. Like a story will talk about "Former President Democrat Jimmy Carter met with...", but never labels the republicans. Also anytime they talk about hilary, they're pretty fair about it, but they often show poorly lit video of her where she looks like a hag. It'll be shot from far away, she'll look chunky or something. MSNBC has full lit standard reel of her.
Also last night, they mentioned Ron Paul earning $4M in a day. Then for no reason at all, Brit Hume says "Ron Paul campaign team denied their ticket was about taking over the govt, just fixing it". I mean, why even put that into the listener's mind, that Ron paul supporters would do such a thing?
FOX doesn't seem to like Ron paul, but many republicans do.
