I think a visitor from Mars watching this debate would have been struck by the fact that Sarah Palin could barely get a paragraph out without mangling what she was trying to say. Conversely, a veteran of the Katie Couric Interviews would be struck by the fact that Palin’s errors weren’t so egregious that you were left totally baffled as to what she was trying to say. But I don’t actually think this stuff is all about expectations. If Palin had some kind of substantial record on or background in national issues, I don’t think anyone would find this performance especially terrifying. But if you already had some serious doubts about her, I think she scarcely put those doubts away.
