If you are familiar with the old CNN version of Crossfire from the 1980s and 1990s, this is what it looks like. Where the two debaters let's say aren't really there to answer the others questions or points, other than to try to turn it around and make it look like something else. Where they are there to actually respond to the other side other than to say what they are there to say. Get their talking points out and to make their case. But not to actually have a discussion with the other side.
If this was a real interview, Dan Rather asks questions or makes points. And then George Bush has the opportunity without being interrupted as long as he's responding to the questions and points about what the interviewer asked. Not trying to respond to every single point that is made before the other has the opportunity to finish their point and make their case. Didn't see that here, what we saw was two people not really talking to each other, but for the most part talking past each other.
