Republican presidential candidate Mitt Romney says US President Barack Obama has no agenda worthy of a second term in office.
At a campaign rally in Florida, he said the Obama campaign had been "reduced to petty attacks and silly word games".
"Have you been watching the Obama campaign lately?" he asked.
"They have no agenda for the future, no agenda for America, no agenda for a second term. It's a good thing they won't have a second term."
Earlier, Mr Obama decried Mr Romney for shifting his positions as election day draws nearer.
The two are due to meet for a final debate on foreign policy in Florida on Monday. The election is on 6 November.
The BBC reports recent polls show an ever-tightening race, including in key election states.
A CNN poll on Friday suggested Mr Romney has a slender 1% lead in Florida, within the poll's margin of error. A separate poll gave a similar edge to Mr Romney in Iowa and New Hampshire.
Control of the Senate again hangs in the balance this year, with the Democrats fighting to hold onto their majority.
