[](https://www.publicpolicypolling.com/pdf/PPP_Release_041408.pdf)Barack Obama continues to hold a big 54 percent to 34 percent lead in North Carolina, where Democrats go to the polls May 6, according to a Public Policy Polling survey conducted April 12-13. In its March 29-30 poll, Obama had led 54 percent to 36 percent, so if any voters heard about his “bitter” remark over the weekend, it showed no signs of hurting him. PPP’s Dean Debnam said it may be that most likely voters had not heard about the controversy or just that Obama has been running so strongly in the state “that it may not cause him much harm even with folks who do know about his comments.”

A majority of voters said it would make no difference if John Edwards endorsed either candidate. Clinton leads Obama by 51 percent to 37 percent among white voters who make up 56 percent of the sample while Obama leads among black voters, who comprise 37 percent, by 81 percent to 10 percent. Obama has big leads over Clinton among both men and women voters.

Forty-four percent of voters named the economy as the top issue compared to 28 percent who cited Iraq.
