I’d like to know what the internals of this poll are. The early Susquehanna poll showing Romney +4 sampled Dems +4. That is simply not realistic in a state where the active registration edge is D+12. At D+8/D+9, which seems more realistic to me for PA in this cycle, that would mean a dead heat. Still, promising. But the newer poll may actually be the same result as before — just with more Dems in the sample.
SP&R used a D+6 sample.
