I continue to be amazed at the apparent inability of cable news programmers to see the obvious patterns in the ratings. On CNN and MSNBC, the most Republican-friendly shows (zahn and tucker respectively) are low-rated. The only "liberal on TV," Keith Olbermann, beats them all. No one is actually watching golden boy Glenn Beck's show, despite his massive promotion all over the place. His show probably costs about 5 cents to produce, but still.
Any sensible person would see that Olbermann's audience generally drops off a lot when Joe Scar comes on the air, and think about how to retain that audience.
