So PPP has Clinton doing better in NC than she is nationally? Riiiiight.
The national PPP poll is already two weeks old, Christie has gotten much higher negatives since then. The first post-scandal reactions were Republicans rallying around him and independents being sceptical to the whole news story. Now there's no doubt anymore among independents that he's guilty and even Republicans have started to somewhat distance themselves from him (and not only Ken Cuccinelli). Hillary would for sure do tremendously better if they polled again nationally today. Although their previous poll probably was an outlier.
On average, polls have Hillary doing 8% better nationally than in North Carolina. That is up from 6% with Obama. Thus so far, North Carolina has not shown itself to be a strong Hillary state.
