US election: Obama and Romney deadlocked for final push

The US presidential candidates are heading into the final two days of campaigning with the outcome still too close to call.

Republican Mitt Romney will campaign in Iowa, Ohio, Pennsylvania and Virginia, while Barack Obama heads for New Hampshire, Florida, Ohio and Colorado.

Both candidates addressed large rallies on Saturday in key swing states.

The latest ABC News/Washington Post survey suggests the pair are level with 48% of support.
