As opposed to Wright and Ayers and bitter and ... Obama just made a lot fewer own goals than his opponents, and then there's the whole temperment thing.
Personally I think the whole "VP's job" thing is a waste of time. Who cares? She was talking to 3rd graders.
I was more concerned about the other bafflegab she was spouting. I think it was obvious that she was unprepared; the job of President is not just about "executive experience" (not to mention Alaska has less population than Rhode Island and many cities). Whether she can learn or not is another matter, but had McCain kicked off 2 months into his first term I believe we would have been in trouble with her at the helm.
Did she get more attention? Probably. But that's what McCain *wanted* to happen. She was chosen to make a big splash. It just didn't turn out quite the way he expected.
