On the last version of NPR’s “Diane Rehm Show,” the assembled liberal reporters were all throwing hardballs at Team Bush over the latest WMD report from the Carnegie Endowment for International Peace. But for the record, can we take a teeny-weeny look at the political backgrounds of the authors?

We have Jessica Tuchman Matthews (former Carter aide and Clinton aide, liberal World Resources Institute, Washington Post editorialist);

we have George Perkovich (former Joe Biden aide, liberal W. Alton Jones Foundation);

and we have the sage of Takoma Park, Joe Cirincione (former aide to Rep. Charles Bennett, anti-SDI Democrat of Florida).

Who wants to bet that absolutely no one in the press notices the less-than-nonpartisan backgrounds of these experts?
