McCain has held significant lead for last four days
PRINCETON, NJ -- Registered voters continue to express a slight preference for John McCain (48%) over Barack Obama (44%) in the latest Gallup Poll Daily tracking presidential trial heat.
These results, based on Sept. 8-10 polling, show McCain continuing to ride his post-convention bounce. He has held a statistically significant lead over Obama in each of the last four three-day rolling averages.
In addition, since Sept. 5 -- the first night after the Republican National Convention -- he has outpolled Obama in each of the last six individual night's polling. That consistent pattern in the night-to-night data suggests that McCain has a stable lead for now.
This is McCain's best performance since late April and early May, when he was ahead of Obama in eight consecutive Gallup Poll Daily tracking reports, which included a campaign-best six percentage point lead. In March, shortly after he clinched the Republican Party's presidential nomination, McCain was ahead of Obama in 19 consecutive Gallup Poll Daily tracking reports.

Both Obama and McCain are taking a break from the partisan campaign to remember 9/11 today. However, the biggest campaign story may be Sarah Palin's first television interview since she was selected as McCain's running mate. She will be interviewed by Charles Gibson of ABC News and the interview will be televised in parts over the next two days. -- Jeff Jones
