(WXIA) -- One week before early voting begins in Georgia's upcoming election, the races are closer than ever.
An exclusive 11Alive News poll conducted by SurveyUSA shows the Senate race tied between the Republican and Democrat candidates. A slightly larger gap exists between the top two candidates in the gubernatorial race.
The results come a day after the candidates squared off during a debate at the Georgia National Fair in Perry.
According to the SurveyUSA poll, Republican Senate candidate David Perdue holds 46 percent of the vote, while Democrat Michelle Nunn has 45 percent. That's close enough for the race to be called even.
SurveyUSA said Perdue holds 77 percent of conservative voters. Nunn holds 87 percent of the Democratic base, but also leads among moderates by 22 points.
Libertarian Senate candidate Amanda Swafford has three percent of the vote, while six percent of voters are undecided.
In the race for governor, Republican incumbent Nathan Deal has a two-point advantage over Democrat challenger Jason Carter -- a change from two weeks ago, when Carter had a slight lead over Deal. Deal has 46 percent of the vote, Carter has 44 percent and Libertarian Andrew Hunt has four percent. Seven percent of voters are undecided.
While Carter leads by seven points among female voters, Deal has polled at 50 or 51 percent among men, meaning Carter is not as strong among women as Deal is among men, according to the poll.
The race for school superintendent is too close to call, with Republican Richard Woods holding 46 percent of the vote and Democrat Valarie Wilson holding 42 percent. Supporters of the Common Core curriculum are more likely to back Wilson, while those who oppose it support Woods.
According to SurveyUSA, 43 percent of those polled said they do not know enough about Common Core to decide whether they oppose or support the standards. Twenty-one percent said they support it, while 36 percent said they oppose it.
In the contest for lieutenant governor, Republican incumbent Casey Cagle holds 51 percent of the vote, compared to Democrat challenger Connie Stokes' 39 percent.
Current Secretary of State Brian Kemp, a Republican, holds 49 percent of the vote in his race, while Democrat challenger Doreen Carter holds 39 percent.
The Republic incumbent in the race for attorney general is also ahead of the Democrat challenger; Sam Olens has 46 percent of the vote, and Greg Hecht has 39 percent.
The margin of error for all questions is 4.2 percent.
