Bruce Bartlett is not a happy camper. He's also completely right on this:

Poynter Online - Forums: From BRUCE BARTLETT, senior fellow, National Center for Policy Analysis: Once again, I just got off the phone with a booker for one of the cable news channels who wanted me to play the role of the knee-jerk Bush supporter and I had to decline. Although I am a conservative who generally supports Republican policies and generally opposes those that come from Democrats, I am uncomfortable being locked into that position. I also don’t think it makes for very good television.

I understand that news shows want to show both sides -- or perhaps I should say two sides -- to controversial issues, lest they appear biased towards one position. But why must this always take the form of a debate? Why can’t they interview a person with one position separately and then interview someone else with another position in another segment? Wouldn’t this be a better way of achieving balance than by always having a debate?

It’s hard enough to make one’s point in sound-bite form without being distracted by the debating tactics of one’s opponent. And, unfortunately, everyone is now trained to know that when one has the camera and microphone they are pretty much free to say what they like, even if it is totally off topic and even untrue. On one occasion, my opponent called me a liar on air at the end of the segment, so that I could not respond. Afterwards, off camera, he conceded that I was right. But no one watching the exchange ever knew that....

The fact is -- and everyone knows this -- that few issues are black-and-white. There are always nuances that are impossible to discuss in a debate format. But the debate format creates the illusion that there is always a simple answer to every complex problem and encourages average television viewers to assume that those of us in the Washington policymaking community are all idiots totally beholden to our party, without a lick of common sense or integrity...
