EXPLAINER: Why AP hasn't called Georgia's close race

WHY AP HASN'T CALLED GEORGIA'S CLOSE RACE

A razor-thin margin and ongoing vote count are what's making the Georgia contest between President Donald Trump and Joe Biden too early to call.

Votes are still being counted across the state, though many from counties where Biden was in the lead.

Biden inched past the incumbent in the tally Friday and by early that evening was leading by 4,020 votes of nearly 5 million ballots cast -- a lead of about 0.08 percentage points. Under Georgia state law, a candidate can request a recount if the margin is within 0.5 percentage points.

THE DETAILS

The Georgia Secretary of State's office said Friday morning that fewer than 8,200 absentee ballots remained to be tallied and 8,900 ballots sent to military and overseas voters had yet to be returned. They must be received by 5 p.m. Friday in order to be counted. It was unclear how many ballots remained to be counted Friday evening.

Gabriel Sterling, an official in the secretary of state's office, said a recount is "more than likely, and the people will see that the outcome will stay essentially the same."

The AP does not declare a winner of an election that will be — or is likely to become — subject to a mandatory recount. In instances where a recount isn't required by law but a candidate requests one, AP will not call a race if the margin between the top two candidates is 0.5 percentage points or less.

Electoral research conducted by the AP found there have been at least 31 statewide recounts since 2000. Three of those changed the outcome of the election. The initial margins in those races were 137 votes, 215 votes and 261 votes.

Among all 31 recounts, the largest shift in results was 0.1%, in the 2006 race for Vermont's Auditor of Accounts. This was a low turnout election in which the initial results had one candidate winning by 137 votes. The candidate eventually lost by 102 votes, for a swing of 239 votes.

Trump and Biden were locked in a tight contest Friday to secure the 270 electoral votes needed to win the presidency. Georgia is a must-win state for Trump, who has a narrower path to victory than Biden. Trump prematurely declared he was winning it early Wednesday morning.

GEORGIA'S POLITICAL PROFILE

Georgia has long been a Republican stronghold. Voters there haven't swung for a Democratic presidential candidate since Bill Clinton in 1992. Trump beat Hillary Clinton there by 5 percentage points in 2016. And the state's government is dominated by the GOP.

But the party's grip has loosened. As older, white, Republican-leaning voters die, they are being replaced by a younger and more racially diverse cast of people, many of whom moved to the booming Atlanta area from other states — and took their politics with them.

Overall, demographic trends show that the state's electorate is becoming younger and more diverse each year. Like other metro areas, Atlanta's suburbs have also moved away from Republicans. In 2016, Hillary Clinton flipped both Cobb and Gwinnett counties, where Biden is currently leading.

In 2018, Democrat Stacey Abrams galvanized Black voters in her bid to become the country's first African American woman to lead a state, a campaign she narrowly lost.

Many political analysts say it's not a question of if but rather when Georgia becomes a swing state. That much was clear in the closing weeks of the campaign as Biden; his running mate, Sen. Kamala Harris; and former President Barack Obama barnstormed the state. Trump, too, visited the state to play defense.
