but that so far hadn't had much impact on their rolling 3-day average.
The current results are based on Aug. 27-29 interviewing, which includes two nights of polling during the convention and one post-convention night on Friday. The Friday interviewing was conducted in an unusual political environment -- the first conducted fully after Obama's well-regarded acceptance speech and McCain's surprise announcement of Alaska Gov. Sarah Palin as his vice presidential running mate. Each event in isolation has usually been associated with increased candidate support for the relevant party. On this day -- with strong partisan forces pushing the public in both directions -- Obama still polled better than he had been prior to the convention, but not as well as he was polling on the individual nights of the convention.
It's good news that on Friday he was still polling better than before the DNC, but apparently the Friday numbers taken separately did not give him the 8-point lead he'd had earlier in the week.
Should have the new poll, which will have Thursday/Friday/Saturday polling, in an hour or two.
