The race for the White House has been the closest and most unpredictable election in American history, a former Australian ambassador to the US says.
As Kamala Harris and Donald Trump make their final pitches to voters ahead of the election on Wednesday, Australian time, former ambassador Joe Hockey said most Americans had already made up their mind on who they want to run the country.
With polling still showing a tight race for the presidency, Mr Hockey said it was possible it would take days after the election to determine who would win the vote.
