Post-Boston, the question seems to be whether the convention gave the Democratic ticket "a bounce." Truth is, Kerry-Edwards has led Bush-Cheney in almost every national poll taken since the North Carolina senator was named as the running mate a month ago. Not by much--3 points, 4 points, 5 points, and in the latest Newsweek poll, 7 points. So the better question is: Is there any way Bush can bounce back? Get ready for that October surprise.
