A format that might be more interesting than four talking heads on three or four subjects, with not enough time to make any points very clear—try the “conservative” Blakely and the “liberal?” Scheer.  One program devoted to Scheer questioning Blankeley on an issue, honestly trying to bring him to say why he supports or opposes this issue or that. (The better the queries and the longer he talks, the clearer the fallacies of his position are exposed.  Next time (if Blakely is “up to it” reverse the tables on another issue and get Scheer to explain why he takes the position he takes.  Advantages:  Better, deeper understanding of “both” sides of single issues. 
  As the format stands, it’s too short to support trying to “discuss” three or four things and ends up being just a sort of “time-share” blather.
