(pre-Ryan)Wapo/Kaiser: Obama +7

[Niemeyerite]

Those are the numbers for all adults and they only show a Dem+9 sample. That is the group that has Obama+12 vs Romney. The RV sample (based on registration % question) are
Dem: 34%, GOP 27%, Ind 33%, or a Dem +7.

Again, where is the bias? 

D+7 is biased... considering that 2012 will be very different than 2008...

D+7 isn't that biased. And the poll isn't either. Do you ever pay attention to the poll 'per se', and not only the partisan sample?
