Donald Trump’s margin in Georgia has fallen from 68,000 to less than 3,500.
Generally a Republican state, it has had 98 per cent of ballots already counted, so Mr Trump and Joe Biden are headed to a photo finish.
Gabriel Sterling, an election official, said it would “take time” to process tens of thousands of remaining ballots. Up to 8000 overseas ballots could still arrive from Service Members.
Fulton County, the state’s largest and home to Atlanta, could tip the state. Donald Trump was leading with 49.6 per cent, while Joe Biden had 49.1 per cent of the vote, but the area is traditionally a Democratic stronghold.
Fulton County elections director Richard Barron told CNN they were “close to being done”: “I think within 2,000 at this point.”
Mr Barron said that factoring in provisional ballots – including the overseas and military votes – meant that the county’s overall count of unknown ballots was nearly 5,000.
Mr Biden is performing better than Hillary Clinton did in 2016, including in their more upscale suburban areas.
Early on Wednesday, Mr Trump prematurely claimed he carried Georgia – and several other states that were too early to call.
“It’s … clear that we have won Georgia. We’re up by 2.5 per cent, or 117,000 (votes) with only seven per cent (of the vote) left” to count, Mr Trump said during an early morning appearance at the White House.
Mr Biden on Wednesday spoke on the election results and told the crowd: “We’re still in the game in Georgia, although that’s not one we expected.”
In Georgia, Republican Senator Kelly Loeffler and Democrat Raphael Warnock have advanced to a January 5 runoff in the special election for Ms Loeffler’s Senate seat.
They’re the top two finishers in a crowded field that also included Republican Rep. Doug Collins. But no candidate was able to get the 50 per cent threshold needed in order to win outright.
Ms Loeffler, a wealthy businesswoman, was appointed last year to replace retiring Sen. Johnny Isakson. Mr Warnock is pastor of the Atlanta church where the Rev. Martin Luther King Jr preached.
Mr Warnock is trying to become Georgia’s first Black US senator.
Georgia is not obvious Biden country. This is the Deep South. No Democrat has taken the state in a presidential election since Bill Clinton 28 years ago.
Georgia joined the Confederacy when it split from the Union. It is deeply religious and deeply conservative. For decades it has been redder than red.
But now the cracks are showing. Polls had Mr Biden and Donald Trump neck-and-neck in the state.
