This is a 3 day tracking poll, which means the days in the poll released today are Monday night, Tuesday night, and last night. Also keep in mind that this poll today, showing Obama gaining a net 5 points on McCain, includes Monday’s polling sample that gave McCain a two point lead. Thus, once that day drops out tomorrow, and Thursday and Friday’s samples are included, the bounce could be even higher.
Convention bounces are going to be interesting to watch this year because of the condensed nature of the schedule. Never before has both conventions been back to back. Indeed, normally the conventions are a month a part, with the challenger’s convention in July and the incumbent in August.
