IF AUSTRALIANS could vote in the United States presidential election, they would choose Barack Obama over Mitt Romney by a margin of 14 to one, a poll shows.

Indeed, Australians prefer the US President by so overwhelming a margin that it would be a bigger landslide than any in the history of the US.

An online poll of 1000 Australians by UMR Research found 72 per cent would vote for the Democrats' Mr Obama, and just 5 per cent for the Republicans' Mr Romney. The biggest share of the popular vote won by any president since the creation of the current voting system was Lyndon Johnson's 61.1 per cent in 1964.

''Australians were behind Obama early - in the 2008 campaign Australia was the third most pro-Obama country in the world, behind Kenya and Italy,'' the chief executive of the US Studies Centre at Sydney University, Geoff Garrett, said. ''It was because of the extraordinary hold-over of negativity towards George Bush and John Howard over the Iraq War.''
