President Barack Obama has resumed his election campaign, which he had suspended because of the devastation caused by superstorm Sandy.
With less than four days to the US presidential elections, one of the latest polls show that the race remains effectively tied.
President Obama is on 47% and challenger Mitt Romney is only one point behind.
