That finding, by Public Policy Polling, is an increase from its survey results in May which found Hagan just barely leading Tillis 38 percent to 36 percent. The new poll also found third-party candidate Sean Haugh getting 11 percent support.
Part of the reason Hagan, who is a top pickup target for Republicans in the 2014 election cycle, is leading Tillis is North Carolinians' general view of the state's General Assembly, according to PPP. Just 18 percent approve of the job the General Assembly is doing while 54 percent disapprove of its job performance.
The poll was conducted June 12 to the 15 among 1,076 North Carolina voters. It had a margin of error of plus or minus 3 percentage points.
The findings seem to be a slight outlier. The TPM Polltracker average for this race shows Hagan leading Tillis 41.9 percent to 38.7 percent.
