Wolf Blitzer just presented the exchange between Obama and Hillary over Wal-Mart and Rezko. But in doing so, he reversed the order. First he showed Hillary bringing up Rezko, and then he showed Obama bringing up Wal-Mart. As presented by Blitzer, it appeared as though Hillary attacked Obama, and he attacked her back. Several bloggers and news accounts have made the same reversal of chronology, including some that did not actually watch the debate live. But Wolf was the moderator. Changing the order changes a lot, IMO.
