As the presidential nominees hopscotched from Pennsylvania to North Carolina to Michigan for explicit pleas in last frenzied hours, Democrat Hillary Clinton urged the people to vote for a big hearted America and said the best days of the country lie ahead.
"Tomorrow, you can vote for a hopeful, inclusive, big-hearted America. Our core values are being tested in this election," she told a crowd in Pittsburgh.
"The choice in this election could not be clearer. It is between division or unity, between strong and steady leadership or a loose cannon," she said taking on her rival Donald Trump.
Meanwhile, Trump, who was campaigning in five states on Monday, criticised the "crooked media," attacked a "corrupt Washington establishment" and mocked Clinton.
"It's a rigged, rigged system. And now it's up to the American people to deliver the justice that we deserve at the ballot box tomorrow," said Trump in Raleigh, N.C.
"They say we'll get a tremendous amount of credit, win or lose. I said: 'No, no, no, no. I don't want any credit if we lose," he said during a rally in Sarasota, Fla.
There are signs that despite the bitter campaign, turnout in states that allow early voting is high, and Americans are seizing the opportunity to express themselves in voting booths, reports the New York Times.
Both Trump and Clinton sent their running mates, families and allies across the country to maximize their reach in crucial swing states.
Trump relied on his three oldest children - Ivanka, Eric and Donald Jr. - as well as Rudolph W. Giuliani, the former New York mayor, and Sarah Palin, the former governor of Alaska and 2008 Republican vice-presidential nominee.
Meanwhile, Clinton deployed President Barack Obama and former president Bill Clinton, as well as Vice President Joseph R. Biden Jr. and the first lady Michelle Obama.
Trump seemed concerned about the lack of celebrity star power for campaign like Clinton, who was accompanied by musicians like Jay Z and Beyonce and was scheduled to campaign in Philadelphia.
"Beyonce and Jay Z. I like them" he said, adding, "I get bigger crowds than they do."
"Is there any place better to be than a Trump rally?" he asked his audience in North Carolina. "We're having fun. And I don't have a guitar and I don't have a piano."
