No one thinks Barack Obama is sitting pretty in this race for the White House. The Real Clear Politics average of the mid-September approval-rating polls measures him at 43 percent approval, 51 percent disapproval. With these numbers, they should be measuring his political coffin. But to listen to the networks talk, it’s the Republican field that is a mess in desperate need of new talent, and its debate audiences are a blood-thirsty horror movie. One place that Democratic contenders go for positive publicity is the network morning shows. Their audiences are diminished, but they remain a powerful national platform, especially for female voters. Rich Noyes and Geoff Dickens of the Media Research Center have demonstrated how ABC, CBS, and NBC set a pretty pleasant table for the Democratic candidates (and potential candidates like Al Gore) from January 1 through July 31, 2007.
