“Compared to a WXIA-TV pre-election tracking poll one week ago, Democrat Michelle Nunn is upside down. 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. Polling for Atlanta’s WXIA-TV 11Alive was conducted by SurveyUSA.
Where in the Senate race is there movement poll-on-poll? 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........”

Rush has shed light on the subject. The phenomenon is wide spread.
The poll results 6 months and more recent than two or three weeks before the election are about shaping public opinion.
Beginning two or three weeks before the election, the reputation of the pollsters comes into play and they become more accurate. They can’t make money if they develop a reputation for being wrong in the end
Is this another case where the pollsters now correct themselves before the election to maintain credibility?
