It seems that Arianna Huffington has run up against the impenetrable wall that is Tim Russert’s ego. Huffington, who is currently on tour for her new book Right Is Wrong: How The Lunatic Fringe Hijacked America, Shredded The Constitution, and Made Us All Less Safe, will be appearing on CNN, ABC, and CBS. She had been booked on Morning Joe and Countdown with Keith Olbermann as well, but those bookings were suddenly and inexplicably cancelled.

NBC confirmed that Huffington wouldn’t be booked on any NBC-affiliated show to promote her book, but refused to explain why. Huffington’s people say that this is Tim Russert’s doing, that Russert is out for revenge because Huffington called him a “conventional wisdom zombie” in her book and devoted seven pages to faulting Russert for allowing his Meet the Press guests to go unchallenged (not to mention HuffPo’s RussertWatch).

OUR KEY FINDINGS:

• Despite previous network claims that a conservative advantage existed on the Sunday shows simply because Republicans controlled Congress and the White House, only one show, ABC’s This Week, has been roughly balanced between both sides overall since the congressional majority switched hands in the 2006 midterm elections.
• Since the 2006 midterm elections, NBC’s Meet the Press and CBS’ Face the Nation have provided less balance between Republican and Democratic officials than Fox Broadcasting Co.’s Fox News Sunday despite the fact that Fox News Sunday remains the most unbalanced broadcast overall both before and after the election.
• During the 109th Congress (2005 and 2006), Republicans and conservatives held the advantage on every show, in every category measured. All four shows interviewed more Republicans and conservatives than Democrats and progressives overall, interviewed more Republican elected and administration officials than Democratic officials, hosted more conservative journalists than progressive journalists, held more panels that tilted right than tilted left, and gave more solo interviews to Republicans and conservatives.

Now that Congress has switched hands, one would reasonably expect Democrats and progressives to be represented at least as often as Republicans and conservatives on the Sunday shows. Yet our findings for the months since the midterm elections show that the networks have barely changed their practices.
