If I heard correctly, it was all Pew: the 52-46 was registered voters; the poll with McCain ahead +1 was likely voters.
By 2012, a lot of the pollsters will be gone/history. Every 5 minutes there is a poll! Also, have you noticed the pollsters throw up 2-3 different models to CYA.
Gallup has been a joke. Three different models...hoping one of them is correct. Death to the MSM and pollsters Nov 4!
