Barack Obama might finally be seeing some bounce out of the star-studded Democratic National Convention.

The Gallup Daily Tracking Poll on Thursday showed the Democratic presidential nominee up 6 points over rival John McCain, 48 to 42 percent, with a 2-point margin of error.

It was the first time in two weeks Obama has opened up a significant lead. McCain even moved ahead of Obama by 2 points in the daily tracking on Tuesday for the first time this summer.

But the Obama bump comes after several high-profile speeches by Hillary Clinton, Michelle Obama, Sen. Ted Kennedy and others praised Obama during two days of convention night speeches.

The Obama and McCain campaigns have been in a tug of war over how high to raise the bar for any post-convention bounce.

McCain spokesman Jill Hazelbaker repeated the campaign's prediction Thursday that Obama will enjoy a 15-point gain coming out of the convention.

But on a conference call with reporters, Obama aides said they expect no bounce at all.

"We don't hold elections in August, we hold them in November," said Obama adviser Anita Dunn. "So, you know, as we move forward out of this convention, we're not expecting a bump, but we feel, frankly ... that we've made a lot of progress this week."

"We expect that ... probably after our convention, after John McCain's V.P. pick, after their convention, that this race will probably be in a very similar place to where it is," Obama spokesman Dan Pfeiffer said.

The Gallup poll was an average of the last three days' results and was taken before Bill Clinton and vice presidential nominee Joe Biden spoke Wednesday night.
