Bill O'Reilly - Basically a populist who leans conservative.
Brit Hume - A genuine conservative, very thoughtful and has little patience for liberal fillibustering or evasiveness.
Fred Barnes - A genuine conservative, not a knee jerk and is much more often than not very fair.
Shep Smith - A hammy guy, leans conservative, folksy.
Sean Hannity - A conservative commentator, relies on sound bites too much.
Morton Kondracke - A thoughtful liberal, not knee jerk and is much more often than not very fair.
Greta Van Susteren - Liberal leaning attorney type. Likes to argue that black is in fact white, not unlike many lawyers who have convinced themselves of their wit, cunning, and brilliance.
Juan Williams - Pretty thoughtless liberal; knee-jerk and bumper sticker mentality.
Alan Colmes - Thoughtful liberal, usually fair.
John Gibson - Fairly conservative, agressive guy. Fair.
Neil Cavuto - Free Marketeer, conservative.
Your list is right on target, except I think that Shep Smith leans more left than right. I didn't like his attitude or comments during the Terri Schiavo case......he came off as surly and sarcastic. Other than that, he does a pretty good job and I think he's passionate about his job.
