Here are part of reports from Politico.com and FiveThirtyEight.com on the Democratic party convention bounce for Barack Obama-Joe Biden.
Politico.com
“Barack Obama met the 50 percent threshold for the first time Tuesday in the Gallup daily tracking poll, a symbolic hurdle that until now had eluded the Democratic nominee.
The Gallup daily tracking poll has found that since the conclusion of the Democratic convention, Obama has risen 5 percentage points in the polls and now leads John McCain 50 percent to 42 percent. That represents a positive turn for Obama, after a couple of days in which he appeared to have peaked at the 49 percent mark while McCain was showing slight improvements.
The survey indicates that Obama’s overall post-Democratic National Convention bounce now appears to be roughly at par with the norm of past conventions. Though smaller than several of the sizable bounces of recent decades, the new polling suggests that perhaps the Democratic convention bounce has yet to subside.
While an improvement from 49 percent to 50 percent is statistically insignificant, the 50 percent mark holds significance for a party seeking to win its first majority since 1976, when Jimmy Carter won with 50.1 percent.”

“A large number of national polls have come out within the past 24-48 hours, most of which had conducted a survey close enough to the beginning of the Democratic convention to provide for a direct comparison. These polls show Obama having gained between 2 and 8 points since before the convention began, or an average of 4.4 points. Although this is slightly below the average convention bounce of 6 points, it is a pretty reasonable result considering that the Republicans had named their VP candidate immediately following the Democratic convention, a circumstance which had never occurred before. Moreover, the internals of these polls show Obama gaining ground among Clinton supporters, a group of votes that John McCain is likely to have a difficult time getting back.
It looks like Barack Obama may have gotten his convention bounce after all:”
