I don’t think this could be right. If so, McCain would have had a pretty good lead before the +17 day for Obama. Just my thoughts.

Not if the polling for Monday & Tuesday was pretty close. In fact, if those days were pretty close, and if McCain was up two on Wednesday, the 46-46 tie between the two on the poll released Thursday morning would make sense. Obambi surely went up huge in the Thursday night polling for the tracking poll to go from a tie on Thursday to a three point Obambi lead on Friday (after several days of Obambi slowly receding).
