With 12 days until the US election, President Barack Obama and Republican rival Mitt Romney are crossing the country looking for every last vote in crucial election states like Ohio, Virginia and Florida.
Mitt Romney spent the day attacking Mr Obama's record on the economy and is now deeming himself the candidate of "change".
But Mr Obama is leading - albeit slightly - in the states that will likely decide this contest.
