We need to be careful, and still look at the internals before cheering. Apparently this poll may be oversampling Republicans. Enough so that the Obama Campaign is squealing like a stuck pig.
Which is the most important aspect of this: in squealing, the Obama Campaign is explicitly acknowledging that the Party ID oversample/undersample matters. That’s a massive win for us, because when all the previous polls were manually unskewed by Freepers and others, they’ve consistently shown the contest even or Romney ahead.
Actually, that is the Pew poll that showed a pretty big GOP lead. It is oversampling Republicans.
