This is when the polls open in each state for the US election 2020
Four more years of Donald Trump, or a new era under Democrat candidate Joe Biden? Today millions of Americans will answer the question of the country’s next president after months of furious campaigning.
Mr Biden edges current incumbent Trump in the polls, with a CNN poll of polls putting his lead at 10 points.
Supporters of Trump will be quick to point at Mr Trump hatching a poll-defying victory in 2016, seeing off bitter rival Hillary Clinton.
Some 90 million Americans have already voted, with those keen to avoid crowds on voting day taking advantage of early voting.
Another 60 million are forecast to head to the polls on election day itself.
