Evening News by Martha

There's been plenty of speculation in the past few months about whether Katie Couric has the credibility to pull off being the first solo female anchor of a network evening newscast. The viewers will decide Sept. 5, and I was willing to give her the benefit of the doubt. But then I saw a promo last night during "60 Minutes" that made me wonder. There's Katie, doing her level best to persuade viewers that "The CBS Evening News" will continue to be the go-to show for serious, though-provoking coverage... while behind her sits a jumbo bouquet of lilies! Did this network ever park a large flower arrangement directly behind Walter Cronkite, Dan Rather or Bob Schieffer? It seems that, even while Couric is striving for credibility, her own network is undermining her.
