The 'Rats cried fraud last summer at Gallup for exactly the same thing (if I remember, Moveon.org came out with an NY Times ad decrying the undercounting of Dems). What pollsters will tell you -- and, not being a pollster, I don't know if this is true -- is that party allegiance fluctuates wildly and that it makes no sense to control for it. If that's the case, both you and Moveon are wrong if the sample is truly random.
Is 27% the same as 37%?
If you want to defend Newsweek for clearly being biased and caught, then you are as conservative as Hillary.
In today's highly partisan political/social environment, do you actually believe that party affiliation fluctuates wildly?! Please!
ALL pollsters control for key demographic variables, Gallup included. The fact Gallup, et al, have decided to stop controlling for the one variable that actually subsumes all the rest speaks volumes!
