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.

In the election for Governor of Georgia, by contrast, there is no poll-on-poll movement. One week ago, incumbent Republican Governor Nathan Deal led by 2 points. Today, he still leads by 2 points. Today, Democratic challenger Jason Carter gets 44%, Perdue gets 46%. Among those voters who tell SurveyUSA they have returned a ballot, Deal leads by 9 points. Runoff-maker Andrew Hunt’s support is down to 3% today, the lowest he has been in 7 tracking polls. The further Hunt’s support drops, the less likely there will need to be a runoff.
