wendy murphy, another easily interchangeable talking head that loves the limelight, stated recently that they are all required to take a pro or con position depending on which pro/con slot needs to be filled during a particular show in order to balance the "debate", for the sake of good tv - she admitted that few if any of them have any real conviction beyond what their dictated role required, which i think is readily apparent when watching any of the primetime tabloid shows. again, thank goodness for schaefer.
