I'm watching it now, and you're right, it is whiney.
I also just saw him on CNN...and I was actually stunned to listen to both Darin Kagan and King present both sides of this issue relatively objectively. They pointed out that Plame's name only came up because Cheney wanted to get to the bottom of who sent Wilson...since it wasn't him as Wilson often implied. They also mentioned the Senate Intel Committee which concluded that Valerie Plame did have something to do with getting Wilson the job in Niger.
