On the panel for This Week with George Stephanopoulos today: conservative George Will, conservative Peggy Noonan, Republican strategist Ed Gillespie, Democrat Robert Reich, Democrat Donna Brazile. Last week’s panel: conservative David Brooks, conservative George Will, journalist Cokie Roberts, journalist Sam Robertson Donaldson (fixed). This is not some aberration; conservative over-representation on political talk shows is a verifiable, repeated phenomenon. Conservatives, your assignment: in 600 words or less, explain to me why a liberal media would continuously disadvantage itself over and over and over again on such shows. No, simply asserting that journalists like Roberts are inherently liberal is not persuasive, considering how desperately they attempt to argue from a neutral POV.
