Here's a spot on description of Christine O'Donnell:

Among the many things wrong with talking-head gab shows, which have proliferated/ metastasized in the past generation -- they're cheap to produce, they fill air time, they make journalists into celebrities, they suit the increasing political niche-ization of cable networks – is that they reward an affect of breezy confidence on all topics and penalize admissions of complexity, of ignorance on a specific topic, or of the need for time to think.

O'Donnell comes across as a perfect, unflappable product of the talk-show culture.

That's James Fallows, whose 1996 essay "Why Americans Hate The Media" remains worth reading as an account of how the dysfunctional relationship between television, politics and journalism came to be.
