US election: Obama and Romney target key swing states

The US presidential candidates have been addressing large crowds ahead of Tuesday's election.

With polls showing Barack Obama and Mitt Romney virtually neck-and-neck, the two men are focusing their efforts on voters in key swing states.

In Ohio, Mr Obama said real progress had been made over the past four years, but that he wanted to continue the fight to give everyone a "fair shot".
Mr Romney told a New Hampshire rally he would lead voters to a "better place".
Barack Obama was campaigning in Ohio, Wisconsin, Iowa and Virginia on Saturday, while Mitt Romney targeted New Hampshire, Iowa and Colorado.
Mr Romney told a crowd in Colorado: "I have got a plan. I can't wait to get going. He [Mr Obama] is hoping we will settle, but Americans don't settle, we build, we aspire, we listen to that voice inside that says: 'We can do better'."
In Virginia, the president was joined by former President Bill Clinton, who said Mr Obama had done "a good job with a bad hand" and deserved another term.
"He [Mr Obama] knows that an economy that builds the middle class and gives poorer people an honourable way to work their way into it is a lot better than four more years of trickle down," Mr Clinton told the rally.
                          
Both candidates were visiting the Iowa town of Dubuque within hours of each other.
Mr Obama, addressing crowds of supporters in Mentor, Ohio, said the election was a choice between "two different visions for America: the top down vision that crashed the economy, or a future built on a strong and growing middle class".
Republican Mr Romney, opening his three-state campaign day in New Hampshire, told supporters to "vote for love of country".
"It is time we lead America to a better place."
Opinion polls suggest the rivals are almost tied, although Mr Obama is slightly ahead in most swing states.
The BBC's Bridget Kendall, reporting from Ohio, says it is hard to predict accurately who might win.
                               But, the Obama campaign has a new confidence in the past week, she says, which may be down to the positive response the president's handling of Sandy storm aftermath has received - a situation Mr Romney has found difficult to counter.
