The answer is simple - no followups. This was something the McCain campaign pushed to get changed. Gwen Ifill was not allowed to ask any followups to any questions. This gave Palin an excuse to dodge questions, which she did really well. So while the pundits are trying to spin this as being some "great performance", it wasn't. It was like moving the outfield wall in by a couple hundred feet and then calling someone the home run king.
