Hatch I do not understand either. Must be some part of the story not well known. As for McCain, that was just obligatory. McCain did elevate her by picking her - and there is a kind of politeness among those in this game just like those inside any other industry. That's all the McCain thing was.
As for Roberts? She explained it, and the Cruz filibuster was a huge factor (did not remember Roberts doing that, but good for him since he did). Occams Razr. it is what it appears to be.
