Obama has 45% to Clinton’s 42% in this week’s survey. Clinton led 46-43 a week ago and Obama was up 45-43 two weeks ago.

Obama’s increase in support since last week comes from small gains across the board. He’s cut Clinton’s margin with white voters, expanded his advantage with black voters, reduced Clinton’s lead with women, and increased his percentage of the male vote.

“PPP has been in the field now in both Pennsylvania and North Carolina since Obama’s ‘bitter’ remarks and has seen no ill effects for Barack Obama,” said Dean Debnam, President of Public Policy Polling. “It doesn’t appear the Clinton campaign has been able to gain any momentum with this issue.”
PPP showed Obama up by 20 points in North Carolina in polling conducted over the weekend, in line with an 18-21 point advantage he has shown over PPP’s last four surveys in the state.

“With our polls consistently showing a close race in Pennsylvania, either candidate has a decent shot at winning this primary,” said Debnam. “It just depends on how good a job each campaign does over the next week.”

PPP surveyed 1095 likely Democratic primary voters on April 14th and 15th. The survey’s margin of error is +/- 3.0%. Other factors, such as refusal to be interviewed and weighting, may introduce additional error that is more difficult to quantify.

PPP will have its final Pennsylvania Democratic poll on Monday.
