I mean, the sample looks pretty decent, but what exactly is the point of releasing an internal showing you tied when other polling shows you ahead? Unless:
1.) The race really is tied (more likely)
2.) They think PPP is going to show a decent Hagan lead in their NC-Sen. poll release this week (less likely)
Maybe they want to encourage their voters to turn out? It always seems in the interest of every candidate to claim that they are in a close race (and therefore your vote/money/activism/whatever could make the difference).
