Republican candidate for governor Brian Kemp has a nominal 2-point advantage but African-American turnout could easily propel Democratic candidate Stacey Abrams to the Statehouse, according to the poll.

With 4 weeks until the midterm elections in Georgia, a new 11Alive poll shows Georgia's gubernatorial race could go either way and every vote is critical.

Republican nominee Brian Kemp has a nominal 2-point advantage over Democrat Stacey Abrams, but African-American turnout could easily propel her into the Statehouse.

The poll, released Tuesday, shows 47 percent of those surveyed support Kemp and 45 percent support Abrams, well within error parameters of the survey commissioned by 11Alive. The contest is best characterized as a "jump ball."

SurveyUSA interviewed 1,250 adults from the state of Georgia Oct. 3 through Oct. 8. Of the adults, 1,027 were registered to vote. Of the registered voters, 655 were determined by SurveyUSA to be likely to vote in the Nov. 6 general election. This research was conducted online.

Abrams, who is African-American, leads 17:1 among black voters, who represent 30 percent of the likely electorate, according to SurveyUSA's modeling. White voters, who make up 64 percent of SurveyUSA's electorate, back Kemp nearly 3:1.

Kemp holds 94 percent of the Republican base (just 5 percent cross-over and vote Democratic). Abrams holds 97 percent of the Democratic base (just 1 percent cross-over and vote Republican).

A concern of Abrams -- something that works well for Kemp -- is independent voting. According to the poll, they break 46 percent to 29 percent for the Republicans. Conservatives break 7:1 for Kemp; liberals break 18:1 for Abrams and the all-important moderates break 5:3 for Abrams, possibly offsetting some of the votes Abrams loses among independents.
