Republican Gov. Nathan Deal and Democratic U.S. Senate candidate Michelle Nunn have slight leads in their respective races within the margin of error of a new statewide poll out today, commissioned by Columbus-area news outlets.

The key findings for governor:

-- Deal: 43.6 percent

-- Democrat Jason Carter: 41.5 percent

-- Libertarian Andrew Hunt: 6.6 percent

For U.S. Senate:

-- Nunn: 44.7 percent

-- Republican David Perdue: 43.1 percent

-- Libertarian Amanda Swafford: 7.4 percent

The automated phone poll of 1,578 likely voters was conducted Aug. 24-25 by Todd Rehm of gapundit.com for WRBL-TV, The (Columbus) Ledger-Enquirer newspaper and PMB Broadcasting radio. The margin of error is +/- 2.47 percentage points, with a 95 percent confidence interval.

The sample contained about 30 percent African-American voters, which is in line with the 2012 share of the electorate -- and Democrats' hopes for a midterm year. Gapundit's Todd Rehm wrote in an email that this figure was determined "based on historical figures and an assessment of trends in voter registration."

We've had a lot of auto-polls lately, many of which show the Republicans ahead in the marquee races. A Landmark Communications survey with live callers conducted two weeks ago showed the Democrats in front.

Rehm shared the full crosstabs with us below, including results on the school superintendent race and ballot questions.
