It's been a long old campaign, but there's only a few more hours to go. With the flurry of last minute activity and results rolling in, let's catch up on what's happened so far.
Before we get started, a quick reminder. In order to win, the candidates need to get 270 or more electoral college votes. Each state has a set number of electoral college votes to hand out, based on population.
1. Trump has 129 Electoral college votes from winning 15 states.
All of these are Republican strongholds in the centre/east of the country. Alabama, Arkansas, Indiana, Kansas, Kentucky, Mississippi, Nebraska, North Dakota, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, West Virginia and Wyoming.
2. Clinton has 97 electoral college votes from winning 9 states.
Clinton's wins so far are also pretty predictable at this point in the race. She's taken Delaware, Columbia, Illinois, Maryland, Massachusetts, New Jersey, New York, Rhode Island and Vermont.
3. Ohio and Florida are incredibly close races.
Unlike in the UK, we hear about the votes as they are counted. This means we can already see that two crucial swing states are on a knife edge. In Florida, Trump has 49% of the votes counted so far, with Clinton taking 48%. In Ohio, the vote stands at 52% for Trump, 44% for Clinton with 41% of voting precincts counted so far.
Trump is ahead again by a small margin in North Carolina, with 50% to Clinton's 48% as just over half of the votes have been counted.
Obviously, this could all change as other areas of these states are counted, particularly cities with high populations.
Some unexpected states are also looking closer than first thought. Virginia and New Hampshire particularly are looking too close to call.
4. Trump has already lodged a complaint.
Trump's campaign announced it was seeking an investigation in the battleground state of Nevada over reports that some early voting locations had allowed people to join queues to vote after polls were scheduled to close.
His team wanted the votes made in those two hours not to be "co-mingled or interspersed" with the rest of the vote cast in early voting. The request was denied by District Court Judge Gloria Sturman.
5. Trump is edging ahead in the popular vote.
Although US presidents are not elected by popular vote, it's an interesting statistic to look at, especially to see how close the two candidates are. At present, Trump has 18,348,382 votes to Clinton's 16,734,212.
6. The polls are still open in 10 states.
The west coast of America is still voting and polls are open for another hour or so.
