Regardless of one's political affiliation, this was a fascinating scene. On display were the unique parts of radio that can be seen but not heard. This was not like watching Howard Stern cracking wise in an enclosed booth while his guests remove their clothes. This was two people sitting eye-to-eye engaging in a frank discussion. Talk radio may not always be like this, but yesterday, with these two foes seated no more than three feet apart, eyes locked, it was.
