US presidential rivals Barack Obama and Mitt Romney are spending the day before the election visiting key swing states and making final pitches to voters.
Romney went to Florida, where polls suggest he has the edge, and then to Virginia, New Hampshire and Ohio.
Obama appeared in Iowa, Wisconsin and Ohio, joined at rallies by Bruce Springsteen and rapper Jay-Z.
The election will be decided in just a handful of states, with Ohio in particular seen as crucial to victory.
Obama and Romney are running almost neck-and-neck in national polls, in a campaign that has cost more than 2 billion dollars.
