That's the fourth poll so far this month which has Hagan winning. There was also the Tillis internal which showed a tie. The state of the race looks clear.
Looks like the "tossup" states of Colorado, Iowa and North Carolina are all pink on the Atlas map now. 
On a somewhat related note, at 538 they note that the Senate Democratic candidates in purple/swing states are "beating the national mood."
