The world is just a day away from sweeping change in America, both presidential candidates have declared.
Front-runner Barack Obama and his Republican rival John McCain started the final day of their campaigns in the key battleground state of Florida as they both aimed to become the 44th president of the United States.
Mr Obama would be the first African American to hold the office and, with Republican running mate Sarah Palin, Mr McCain would bring the first female vice president to the White House.
"We are one day away from changing the United States of America," Mr Obama told thousands of supporters in Jacksonville.
"Tomorrow, you can turn the page on policies that put greed and irresponsibility ahead of hard work and sacrifice.
"Tomorrow, you can choose policies that invest in our middle class, create new jobs, grow this economy so that everyone has a chance to succeed, the CEO and the secretary, the factory owner and the men and women on the factory floor.
"Tomorrow, you can put an end to the politics that would divide a nation just to win an election, that tries to pit region against region, city against town, Republican against Democrat, that asks us to fear at a time when we need to hope.
"Tomorrow, at this defining moment in history. You, each and everyone of you, can give this country the change that we need."
He said an Obama presidency would "change the world".
The 47-year-old Illinois senator leads Mr McCain by seven points in the latest average of national polls by RealClearPolitics.com and more than double the number of electoral college votes, 270 of which are needed to win the presidency, are considered to be safely in the hands of the Democrat than his rival.
Earlier, in Tampa, Mr McCain told cheering supporters: "With this kind of enthusiasm and this kind of intensity, we will win Florida and we will win this race.
"There's one day left until we take America in a new direction, my friends.
