One week ago, Nunn led Republican David Perdue by 2 points, 46% to 44%. Today, in a dramatic reversal, Perdue is on top, 48% to 45%, a 5-point right turn in one of the nation’s most high-visibility contests.So, huh? Is this real movement? A statistical blip? They make a lot of that "5-point right turn" when, honestly, all of this is within the margin of error. There's some interesting stuff, though. For example:
Among women, where Perdue had trailed by 13 points and now trails by just 2. And among core Republicans, where Perdue’s 84-point advantage is the largest it has been in 7 WXIA-TV tracking polls going back to 08/18/14. There is movement to Perdue among seniors, where he now leads by 25 points. Worse for Nunn: among voters who tell SurveyUSA they have already returned a ballot, Perdue leads by 10 points.That doesn't bode well for you Nunn fans. Yes, this is a robo-poll, but so was the previous one.
If I have time, I'll dig deeper into the weighting and such to try and understand what, if anything, is happening.
