Donald Trump is projected to take North Carolina and Georgia – two of seven crucial states that will decide the election.
We are now awaiting the outcome of the others: Arizona, Michigan, Nevada, Pennsylvania and Wisconsin.
Meanwhile, the Republicans are also set to take control of the Senate.

To win the presidency, a candidate needs 270 out of 538 electoral college votes.
Each state is worth a differing number of electoral college votes depending on the size of the population. In most cases if a candidate gets the most votes in a state, they win all the electoral college votes for that state.
One to watch out for is Pennsylvania. With its 19 electoral votes, it could be the key to any win. We may not know the result here for several hours.

The map above shows how voting is going in each county of Pennsylvania.
Donald Trump is likely to get more votes in the rural areas in the centre of the state.
If Kamala Harris is to win, she needs to do well in the densely populated suburbs of the major cities.
Watch places like Montgomery, Bucks, Delaware, and Chester counties around Philadelphia and Allegheny county that covers Pittsburgh.
Erie (in the north-west of the map), Northampton (half way down the east side) and Luzerne (to the east of Scranton) are all counties that voted for Trump in 2016 and switched to Biden in 2020.
The vote shares and leads will change as votes are counted during the night. Keep an eye on the estimated percentage of the vote that has been counted to know how far through they are.
Republicans projected to control Senate
There are also elections to both Houses of Congress. The Republicans are projected to have gained a majority in Senate after wins including West Virginia and Ohio.

If the President’s party controls both these institutions it gives him or her a good chance of implementing their agenda.
If either House is in the hands of the other party, more negotiation will be needed.
What exit polls tell us about how people voted
The US exit polls help build a picture of how different groups of people have voted across the nation.
The latest numbers suggest that women are breaking for Kamala Harris but perhaps not by the margins her campaign had hoped, at 54% compared with 44% for Donald Trump.
In 2020, the exit polls suggested 57% of women backed Joe Biden, which is broadly similar once the margin of error is taken into account.
Exit poll data is updated throughout the night so the picture may change.
Looking at race, Trump is leading among white voters – the biggest single group – and Harris is leading with black voters.
She is also ahead with Hispanic voters but it looks like support for Trump has increased more than 10 points among this group compared with 2020.
A majority of younger voters are backing Harris while just over half of middle-aged voters are voting Trump, the latest data suggests. The over-65 age group is evenly split.
Nearly six in 10 college-educated voters in the data said they voted Harris, while a similar proportion of people without a college degree voted for Trump.
