Certainly not surprising. I listen, watch, and read all of those sources and there is no question there are subtle and not so subtle biases that are present with all of them. Fox News is the whipping boy of the left and NPR of the right. In the case of Iraq, NPR clearly has done a better job. Other stories, I think we would get different results.
