I watched the speech last night, and I found her to be witty, intelligent, and generally a breath of fresh air to the campaign. I also noted that listening to most commentators on several networks, the consensus was that she hit a home run. Whether the commentator agreed with her politics, there seemed to be a general agreement that she delivered a great speech.
Maybe I was watching something different than most of this thread, but I thought it was superb. I also thought Ted Kennedy gave an inspired speech and Obama and his wife also delivered excellent speeches. I thought Fred Thompson gave a very excellent speech as well as Rudy Guliani. Of course, I was trying to be objective.
