Pearce: McCain is closing the gap fast in the daily tracking polls as they begin to cover the Convention. The latest from Gallup shows a 8 point lead for Obama evaporating to 2. The next two polls to come out will cover the complete convention, including the speeches of Palin and McCain. I expect the gap to tighten more and perhaps McCain take the lead. A CBS News poll early last week, already showed a tie. The Palin pick is indeed boosting the polling numbers for the ticket. Rasmussen finds that she is more popular than both Obama and McCain and far ahead of Biden.
