Regardless of what NPR program that I happen to turn on, other than Marketplace (and, sometimes even it), every subject, interview, and opinion are left-leaning, and sometimes to an extreme.
Although a liberal bias is nothing new at NPR, I have been listening to NPR for almost forty years and I can honestly say that there is essentially no reporting or interview that supports anything that has a conservative point of view, or does it incorporate an objective discussion with anyone who represents a more conservative position on a subject.
NPMSNBC or CNNPR would be more befitting than NPR, because NPR only takes the side of a portion of the "public".
After the Juan Williams debacle, you would think that NPR would have changed its ways, but sadly, nothing has improved in giving its listeners a truly objective source of information.
