On Friday, the network morning shows downplayed or ignored 2008 Democratic presidential candidate Barack Obama’s muddled comment that nuclear weapons shouldn’t be used in "any circumstances" in Afghanistan or Pakistan. On CBS, the "Early Show" didn’t cover the story at all. During the three hour broadcast of the "Today" show, NBC found time for only one brief anchor read.

ABC’s "Good Morning America" provided the most coverage, but that simply amounted to a solitary anchor brief and then a quick, defensive summery of Obama’s statement by "This Week" host George Stephanopoulos:

George Stephanopoulos: "...Barack Obama, appearing to rule out the use of nuclear weapons in going after al Qaeda or the Taliban in Pakistan....What he's drawing fire for though is talking about it. A lot of nuclear strategists say you should never talk about how or when you're going to use nuclear weapons. The Barack Obama people though say they make no apologies. They're not going to back down at all and that they’re saying, uh, the correct policy that people need to hear."

On Tuesday’s "Good Morning America," anchors Robin Roberts and Diane Sawyer touted the marital relationship between Democratic presidential candidate John Edwards and his wife. Co-host Robin Roberts recounted the often repeated story of how the Edwards couple spend their wedding anniversary, including their recent 30th, at the restaurant Wendy’s.

Roberts, perhaps in a Freudian slip, even referred to the former North Carolina Senator as "presidential nominee John Edwards." Sawyer gushed that the candidate and his wife "are going to renew their vows." "Happy anniversary," she added.

Yet, this is the same morning show that has vastly underplayed stories that aren’t quite so cute and endearing for the '08 contender. For instance, during a recent GMA town hall with John Edwards on the subject of poverty, Ms. Sawyer only managed to mention the trial lawyer’s 28,000 square-foot mansion once.
