ATLANTA -- Election officials across Georgia were expected to complete a hand tally of the presidential race Wednesday night, which would allow state officials to begin the process of certifying the election results, a top elections official said.

The hand recount of about 5 million votes stems from an audit required by a new state law and wasn't in response to any suspected problems with the state's results or an official recount request.

The deadline for the counties to complete the audit was 11:59 p.m. Wednesday, ahead of the Friday deadline for state certification. Gabriel Sterling, who oversaw the implementation of the state's new voting system, said he expects the counties to meet that deadline. He said the secretary of state's office plans to release a report on the audit Thursday.

The hand count is meant to ensure that the state's new election machines accurately tabulated the votes and isn't expected to change the overall outcome, state election officials have repeatedly said.

Going into the count, Democrat Joe Biden led Republican President Donald Trump by a margin of about 14,000 votes. Previously uncounted ballots discovered in four counties -Douglas, Fayette, Floyd and Walton - during the hand count will reduce that margin to about 12,800, Sterling said.

A law passed last year requires the audit but leaves it up to the secretary of state to select the race to be audited. Secretary of State Brad Raffensperger said he chose the presidential race because of its significance and tight margin. Because of the close results, he said, a full hand recount would be needed to complete the audit.

Once the results are certified, if the margin between the candidates remains within 0.5%, the losing campaign has two business days to request a recount. Sterling said he hoped the hand tally affirming the result of the election would be enough to convince everyone that the election results were sound, but he said a recount would be done if requested.

“I'm hoping that we won't have to put the counties through that level of work,” Sterling said. “But if that request comes through, it's a lawful request.”

A recount would be done using scanners that read and tally the votes and would be paid for by the counties, Sterling said. He said he didn't know how long it would take because they've never done a statewide recount on the new machines.

Marc Elias, a prominent election lawyer who has been involved in litigation surrounding the election on behalf of Democrats, said during a call with reporters organized by the Biden campaign that the hand tally has confirmed Biden's lead. A request by the Trump campaign for an additional recount would be wasteful, he said.

“In the end, more voters voted for Joe Biden than voted for Donald Trump and there isn't any amount of recounting of these ballots that's going to change that fact,” Elias said. “All it's going to do is waste the taxpayers money.”

Over the two weeks since the election, Raffensperger has been under attack from fellow Republicans, from the president on down.

Raffensperger has steadfastly defended the state's handling of the election and the subsequent audit. He has said his office has seen no evidence of widespread voting fraud or irregularities and he was confident the audit would affirm the election results.

In addition to other complaints, Trump and other critics have incorrectly claimed that Georgia election officials are unable to verify signatures on absentee ballot envelopes because of a legal settlement known as a consent decree. There is nothing in the consent decree that keeps election workers from checking those signatures. In fact, Georgia requires that they be checked.

When Georgia voters return an absentee ballot, they have to sign an oath on an outer envelope. County election office workers are required to ensure the signature matches the one on the absentee ballot application and the one in the voter registration system, Raffensperger has said.

Raffensperger's office said in a Wednesday news release that the rate of absentee ballot rejections in the general election was 0.15%, which matched the rate in the 2018 general election. The actual number of rejected ballots was about 350% higher, but that matched the overall increase in absentee ballots, the release says.

In this year's general election, 2,011 ballots were rejected for missing or nonmatching signatures out of 1,322,529 ballots returned. Two years ago, 454 absentee ballots were rejected out of 284,393.

The Associated Press has not declared a winner in the presidential race in Georgia, where Biden led Trump by 0.3 percentage points. There is no mandatory recount law in Georgia, but state law provides that option to a trailing candidate if the margin is less than 0.5 percentage points. It is AP's practice not to call a race that is - or is likely to become - subject to a recount.
