Donald Trump is projected to have won the first two of the seven swing states to be declared – narrowing Kamala Harris’s routes to the White House.
Trump and Harrisboth need to hit the magic 270 Electoral College votes to become the next US president.
Trump wins are projected in they key battlegrounds of North Carolina and Georgia.
Losing there could indicate that any route for Kamala Harris has to go through the “blue wall” states – Pennsylvania, Michigan and Wisconsin – which are all tight battlegrounds.
Votes are still being counted, and counting is generally more complicated in the US than in the UK, largely due to the country’s sheer size; the varying time differences alone make for a longer process.
Polls began closing at 11pm UK time and the last of them closed at 4am UK time.
In many past elections, it’s at around this time that a winner has been declared.
Before we get into those factors in detail, you need to know how a winner is declared.
How calling the election works
When a winner is declared, whether it’s hours or days from now, it will initially be a “projected” winner.
It’s projected because the official results are typically only confirmed by state officials after 7-30 days, depending on the state.
Sky News has access to the most comprehensive exit poll and vote-counting results from every state, county and demographic across America through its US-partner network NBC.
Big voter turnout
There are some 240 million people eligible to vote in the US.
And if voter turnout is particularly high, it means vote counting will take longer than usual.
This was the case in 2020, when a record 158.5 million people voted – the highest turnout since 1900.
It isn’t yet known how many voters have visited the polls on election day, but more than 77 million Americans had already cast their votes by Monday, according to the University of Florida’s Election Lab – 42,195,018 returned in person and 35,173,674 by mail.
Many also said it was because more people – around 100 million – voted by post than usual due to the COVID-19 pandemic, and those votes took longer to count.
Election officials have been optimistic that the 2024 vote count will be smoother without the many challenges the pandemic posed to officials in 2020, according to NBC News.
But you’ll have seen overnight that Ms Harris and Mr Trump were projected winners in certain states early on after polls closed.
These are states where votes are so clearly leaning in one direction as they get counted that there is too much ground for the trailing candidate to make up.
In those swing states, however, voting is going to be far closer, and a winner will not be projected until the NBC News decision desk is certain of an outcome.
That could mean waiting until practically all the votes in some of the states are in to project a winner – which could take days.

Key terms to listen out for as the count progresses
There are a number of key stages between now and reaching a projected winner, NBC News says. Listen out for these calls:
Too early to call: This can mean two things: there might be a significant margin for one of the candidates, not enough to meet NBC’s statistical standards to project the race; or there is not enough data to determine the margin with certainty.
Too close to call: This means the final margin between the candidates will be less than five percentage points. NBC News’ decision desk will not use this characterisation until it has statistical confidence that the race will be this close.
Leaning: This status is introduced when the decision desk is confident that the candidate who is ahead is going to win, but the statistical threshold for calling the race has not yet been met.
Projected winner: NBC News has made a projection that a candidate will win.

It’s common in the US for it to take a couple of days to know who the next president will be.
The 2020 election’s four day wait was an anomaly, but it paled in comparison to the 2000 election, when it took weeks.
Florida and its 25 Electoral College votes (it now has 30) were set to decide the contest between Democrat Al Gore and Republican George W Bush, whose brother was Florida governor.
On election night on 7 November, TV networks called the state for Gore before polls had closed everywhere in the state. Later that evening, they reversed their stance and said it was too close to call, then called it for Bush and then returned to “too close to call”.
A preliminary vote tally the day after the election had Bush ahead by around 1,700 votes in Florida – so close that state laws triggered an automatic machine recount. The first recount winnowed Bush’s lead down to just 317 votes.
The issue was around Florida’s punch-hole ballots and hanging chads – punched holes that might still have a corner intact – and how these were counted.
A legal battle ensued that went right up to the US Supreme Court, which in a 5-4 decision along ideological lines ruled that any solution to the recount issue could not be put in place by the deadline, thus handing the state to Bush.

What happens after a winner is declared?
Whether a winner is declared on the night or in the following days, they aren’t officially elected until the electoral votes are formally cast and counted.
Electors cast them on 17 December, they are counted and certified by Congress on 6 January and then the new president will take office after being inaugurated on 20 January.
Unlike the general election in the UK, there is a transition period between the election result and the new president taking over.
During the gap, Mr Biden will continue as president, with the election winner known as the president-elect until the transfer of power in January.
A man has been taken into custody two days after a US politician and her husband were shot dead in Minnesota, law enforcement officials have said.
Authorities had urged the public not to approach Vance Boelter, 57, who they warned could be armed, and who was reportedly posing as a police officer.
A massive manhunt was launched on Saturday after Melissa Hortman and Mark Hortman were shot dead at their home in Minneapolis in what Minnesota governor Tim Walz called a “politically motivated assassination”.
Police said the same gunman that killed the Hortmans had earlier shot and wounded Democrat senator John Hoffman and his wife, Yvette, at their home nine miles away.

Boelter was arrested on Sunday evening in a rural area in Sibley County, southwest of Minneapolis.
He faces two counts of second-degree murder and two counts of attempted second-degree murder in the deaths of the Hortmans and the wounding of Hoffman and his wife.

Police said they responded to gunfire reports at the Hoffmans’ Champlin home shortly after 2am on Saturday and found them with multiple gunshot wounds.
They then checked on the Hortmans’ home, in the nearby Brooklyn Park suburb, and saw what appeared to be a police car and a man dressed as an officer leaving the front door.
“The individual immediately fired upon the officers, who exchanged gunfire, and the suspect retreated back into the home” and escaped on foot, said Brooklyn Park police chief Mark Bruley.
Authorities believe Boelter wore a mask as he posed as a police officer, and also used a vehicle resembling a squad car.
Several AK-style firearms and a list of about 70 names, which included politicians and abortion rights activists, were allegedly found inside the vehicle.

Governor calls it ‘targeted political violence’
‘We are both incredibly lucky to be alive’
Senator Hoffman was shot nine times and is having multiple surgeries, according to a text message shared on Instagram by fellow senator Amy Klobuchar on Sunday.
The text from Yvette Hoffman added: “I took 8 and we are both incredibly lucky to be alive.”
She said her husband “is closer every hour to being out of the woods”.
Mrs Hortman used her position to champion protections around abortion rights, including laws to cement Minnesota’s status as a safe refuge for people from restrictive states, who travel there for an abortion.
Her work also sought to introduce protections for services that provide abortions.
A manhunt is continuing after the gunning down of a Democrat politician and her husband – with police saying they’re acting on the assumption he is still alive and dangerous.
Melissa Hortman and Mark Hortman were shot dead at home in a Minneapolis suburb on Saturday in what governor Tim Walz called a “politically motivated assassination”.
Democrat senator John Hoffman and his wife were also shot multiple times at their home nine miles away, but survived.
A search is under way for Vance Boelter, 57, who authorities believe wore a mask as he posed as a police officer, and also used a vehicle resembling a squad car.
Several AK-style firearms and a list of about 70 names, which included politicians and abortion rights activists, were found inside.

Boelter was last caught on camera wearing a cowboy hat – a similar hat was found near another vehicle belonging to him on Sunday.
Authorities said at their latest news conference they assume he is still alive.
Hundreds of police officers are searching for Boelter, who escaped from the Hortmans’ house on foot after an exchange of gunfire.
Senator Hoffman was shot nine times and is having multiple surgeries, according to a text message shared on Instagram by fellow senator Amy Klobuchar on Sunday.
The text from Mr Hoffman’s wife, Yvette, added: “I took 8 and we are both incredibly lucky to be alive.”
She said her husband “is closer every hour to being out of the woods”.
“We believe [Boelter’s] somewhere in the vicinity and that they are going to find him,” Senator Klobuchar told NBC’s Meet the Press.
“Everyone’s on edge here,” she added, “because we know that this man will kill at a second.”

Neighbours of killed US politician stunned
Police said they responded to gunfire reports at the Hoffmans’ Champlin home shortly after 2am on Saturday and found them with multiple gunshot wounds.
They then checked on the Hortmans’ home, in the nearby Brooklyn Park suburb, and saw what appeared to be a police car and a man dressed as an officer leaving the front door.
“The individual immediately fired upon the officers, who exchanged gunfire, and the suspect retreated back into the home” and escaped on foot, said Brooklyn Park police chief Mark Bruley.
Another vehicle belonging to Boelter was searched on Sunday in Minnesota’s Faxon Township. A cowboy hat similar to the one seen in the police appeal was found nearby.
It’s been revealed that the suspect texted friends around 6am on Saturday to say he had “made some choices” and was “going to be gone for a while”.
According to AP, which has seen the messages, he reportedly said: “May be dead shortly, so I just want to let you know I love you guys both and I wish it hadn’t gone this way… I’m sorry for all the trouble this has caused.”

Governor calls it ‘targeted political violence’
Records show Boelter – a father of five – is a former political appointee who served on the same state workforce development board as Mr Hoffman.
However, it’s unclear to what extent they knew each other, if at all.
Mr Hoffman, 60, was first elected in 2012 and runs a consulting firm called Hoffman Strategic Advisors.
Melissa Hortman, a 55-year-old mother of two, was first elected in 2004 and was the top house Democratic leader in the state legislature.
She also served as speaker of the Minnesota House of Representatives.
Mrs Hortman used her position to champion protections around abortion rights, including laws to cement Minnesota’s status as a safe refuge for people from restrictive states, who travel there for an abortion.
Her work also sought to introduce protections for services that provide abortions.

Neighbours of killed US politician stunned
Friends of Ms Hortman have told Sky News that her two children feared for their mother’s life after reading divisive rhetoric directed at her online.
Matt Norris, another political colleague of Ms Hortman, was also at church, reflecting on the rise of political violence in America.

“We’ve going to have to do some serious introspection as a state, as a country, and figure out how do we get beyond this,” he said.
“How have we been laying the seeds that have led to horrific acts of violence against public servants like this?
“And it’s going to be incumbent upon us as leaders to set a different tone, to set a different direction for our state and our country so that horrific tragedies like this never occur again.”

But there’s no sign of division at the State Capitol Building, where flags fly at half-mast and flowers are being left in tribute.
This is a community united in grief and in its hope for an end to gun violence in America.
