"SourceWatch.org"? Sounds very reputable.
I have just spent 20 minutes there. They lean heavily left for their citations and their selective use of language is quite telling. For example, neutral or unobjectionable terms are used to describe orgnizations like MoveOn.org, which is merely a "liberal advocacy" group founded in 1998 as a "bipartisan email group", whereas the likes of Swift Boat Veterans For Truth was financed by a billionaire "hardline rightwinger" and is guilty of a "propaganda smear campaign". No pretence of objectivity or fairness whatsoever.
