Republican presidential candidate Mitt Romney met voters at an election rally in Nevada on Wednesday, during which he said the Obama campaign was "slipping and shrinking".

It came as Romney edged one percentage point ahead of President Barack Obama in Reuters/Ipsos daily tracking poll, in an election race that is effectively a dead heat.

With the debates over, Romney has turned his attention to voter contact and in recent days his campaign has focused on the argument that Obama has not offered an agenda for his second term.

The Republican candidate said: "The President doesn't understand what it takes to get this economy moving.

"He doesn't have a plan to get jobs for Americans.

"I do and that's why I'm going to win."

Commentators say the gap between Obama and Romney, in the race for the White House, is statistically insignificant.
