What does the new hour-long show that replaced CNN's Parker Spitzer look like now that Parker is gone? Well, as it turns out, there haven't been a lot of people curious enough to find out. Indeed, instead of the usual "curiosity boost" for a new show, ratings have fallen for In the Arena , which has put Elliot Spitzer in the driver's seat with guest contributors riding along. (Currently they are conservative commentators E.D. Hill and Will Cain.) The show launched Monday with a fourth-place (among cable news shows) 124,000 viewers in the key 25-54 demo. By Wednesday the number had declined to 114,000. By contrast, Bill O'Reilly attracted 895,000 in the demo on Fox News.
