Hagan leads North Carolina state House Speaker Thom Tillis (R) by 47 percent to 39 percent, and matches that margin against state Senate President Pro Tempore Phil Berger (R), who is still considering the race. She holds similar leads over a number of other Republicans considering the race, including former U.S. Ambassador Jim Cain (R) and Rev. Mark Harris (R).

The results are similar to what PPP found when they polled the state last month. Hagan pulls around 46 percent to 48 percent against a field of fairly unknown challengers, a good but not great position to be in for an incumbent senator.

A potential issue for both Tillis and Berger: A strong majority of voters said they disapproved of the work the state legislature has done in the last year. Tillis and Berger have helped push through a number of controversial bills on issues ranging from abortion to taxes to gun control, and by 30-point margins voters say they disapprove of the legislature's work and would be less likely to vote for someone who was involved in that work.

The automated poll of 600 North Carolina voters was conducted from Aug. 8-11 and has a margin of error of plus or minus 4.4 percentage points.
