According the survey taken following the primary earlier this month, Democratic nominee Walter Dalton is beginning to close the gap with Republican candidate Pat McCrory.
McCrory now holds a 46-40 advantage over Dalton after leading 50-35 in the first poll conducted in late January.
PPP said the shift in Dalton's favor could be attributed to an improvement in his favorability. Meanwhile, McCrory's name recognition and favorability has remained mostly unchanged.
The group surveyed 666 North Carolina voters through automated telephone interviews from May 10 to 13.
PPP noted that the poll was not paid for or authorized by any campaign or political organization and the margin of error for the survey is +/-3.8%.
