This would mean that instead of 5.7% difference there is a 1% difference and the poll as therefore oversampled by 4.7%.As covered earlier this poll is using a 7.6% differential, not a 5.7. And the 1% difference is from the Gallup poll, based on random selection. So one poll using another poll's statistics for weighting purposes would be a risky proposition.
I was misled by your reference to the gap being 5.7%. If the gap is as calculated by Rasmussen to be 7.6% and the gap as calculated by Gallup is 1% then the potential error is all the more to McCain's favor, correct?
Wouldn't that mean that 6.6% more Democrats were sampled by Rasmussen than the new reality supplied by Gallup requires? Would not one expect 80% plus of these 6.6% to support McCain? I do not understand why the differences in methodology between Rasmussen and Gallup have to do with establishing the correct ratio of Republicans and Democrats.
Could you kindly explain?
