If this was any outfit but PPP, I'd be worried. Ras at D+3 is oversampling Ds and still only has Obama +1 and still not at 50. The absentee numbers are tightening, but Rs still have decisive, often dominant leads or turnarounds from 04. But I'll admit, could be surprised on election night.
More than likely, though, it's the Ds who will be surprised.
I have no doubt it will tighten as we get closer with early voting. The goal is to just prevent the utter domination of 2008 in that regard by the Dems. I see no way they make up the difference unless no GOP do the in-person early voting later.
