When will we know the result?

The US goes to the polls on Tuesday. Results will start to come in on Wednesday from about 11am AEDT (8am in Perth) when some states close their polling stations on the eastern seaboard of the US. Some states with clear majorities for Hillary Clinton or Donald Trump will be called very quickly. Depending on how close it is and how certain key states fall, the final result could be known anywhere between 2pm AEDT and the early evening. Bear in mind that 4pm in Sydney is midnight in New York, so it is likely that Clinton and Trump will speak to supporters sometime late Wednesday afternoon AEDT.
We’ll be getting results from Michigan and Pennsylvania from around noon AEDT, though it may take a while to know who has won in either place. If Trump pulls off a surprise in Michigan, he will be in a strong position. The result in Pennsylvania will be a big indicator one way or the other, followed by Arizona, New Hampshire and North Carolina.
Many Trump-supporting states will call early. At about 3pm Clinton will win California – and, if she’s going to win the presidency, this could put her ahead on the day for the first time. We may well have a result by 4pm.
