NC: PPP: Romney +.2

[J. J.]

Are you wondering why I think PPP might have a house bias?  

Really sort of doubt PPP is skewing its result.  Isn't it based in NC. And, at this stage, this is game time for pollsters. They know their reputation (and future revenue) are at stake. Almost no incentive for a polling firm like PPP, to not produce as accurate result as possible.

It is not intentional.  It is something internal to their polls.
