CSPAN Callers Are Stupid

I rarely watch CSPAN, but my brother loves it and he's staying with me this week so I caught a bit last night. The thing that really stood out to me was how stupid the callers were and how ill-formed and absurd were many of their points. Maybe there aren't a lot of callers to choose from, or maybe the screeners don't know what they're doing, but the people who call in to talk radio programs generally seem to be quite a bit more knowledgeable and coherent. Then again, many talk radio programs probably have a much larger audience than does CSPAN.
