U.S. Democratic presidential nominee Joe Biden said he isn't making any predictions about the outcome as the final hours of voting ticked down on Election Day on Tuesday.
Republican incumbent Donald Trump, meanwhile predicted his victory as he visited his campaign headquarters in Virginia on Tuesday, but acknowledged he could lose, hours after he said he would not "play games" and declare victory as the results began to come in.
Speaking to reporters outside a Delaware community center, Biden said he's "superstitious" about offering predictions for election night but remains "hopeful."
The former vice president said he had heard from aides that there's "overwhelming turnout" among young people, women and older Black adults in places like Georgia and Florida.
"The things that are happening bode well for the base that has been supporting me -- but we'll see," he said.
Still, he admitted, "It's just so uncertain" because of how many states are in play.
Biden also wouldn't commit to commenting on any results on election night, even if Trump does weigh in on the vote.
"If there's something to talk about tonight, I'll talk about it," Biden said. "If not, I'll wait till the votes are counted the next day."
Supporters cheered and applauded Trump he arrived at the Republican National Committee's annex in Arlington, to thank dozens of staffers working to get him reelected.
"I think we're going to have a great night, but it's politics and it's elections and you never know," the president said.
He said his campaign was doing well in states like Florida, Arizona and Texas. He noted the importance of winning Pennsylvania.
"Winning is easy. Losing is never easy," he said. "Not for me it's not."
The president went to the headquarters just outside Washington after days of grueling campaigning on the road.
"After doing that many rallies, the voice gets a little choppy," Trump said with his now-gravely delivery.
Trump said success will bring unity. He listed what he believes are his accomplishments with the coronavirus and the economy.
More than 100 staffers, almost all wearing masks, lined up against the back wall of the operations center to hear from their candidate.
Nearly 100 million Americans voted early and Election Day voters ended a campaign dominated by the coronavirus and defined by tensions over who could best address it.
Biden entered Election Day with multiple paths to victory while Trump, playing catch-up in a number of battleground states, had a narrower but still feasible road to clinch 270 Electoral College votes.
Control of the Senate was at stake, too: Democrats needed to net three seats if Biden captured the White House to gain control of all of Washington for the first time in a decade. The House was expected to remain under Democratic control.
Earlier Tuesday, Biden headed to Philadelphia and stopped by a carpenters' union hall and visited his childhood home and church in his native Scranton as part of a get-out-the-vote effort before awaiting election results in his hometown of Wilmington, Delaware.
His running mate, Sen. Kamala Harris, was visiting Detroit, a heavily Black city in battleground Michigan. Both of their spouses were headed out, too, as the Democrats reached for a clear victory. Harris later headed to Delaware to join Biden as the polls closed.
Biden and his wife, Jill, started the day with a stop at St. Joseph's on the Brandywine in Wilmington, Delaware, with two of his grandchildren in tow. The four then walked to his late son Beau Biden's grave, in the church cemetery.
Beau, a former Delaware attorney general, died of brain cancer in 2015 and had encouraged the former vice president to make another White House run.
Biden then returned to his roots on his final day of campaigning with a visit to his childhood home in Scranton, Pennsylvania, where he lived until he was 10 years old.
The former vice president arrived at the small, white two-story house to a hero's welcome of more than 100 people cheering across the street.
Biden greeted the crowd and said, "It's good to be home!"
He walked up the front steps and chatted with the current owners before going in with his granddaughters. When Biden came out, he said the current residents had him sign their wall.
Biden then walked across the street to greet the crush of supporters, who cheered his name and applauded.
Trump said he felt good about his chances for victory as Election Day opened, predicting that he would register big wins in key states such as Florida and Arizona.
"We feel very good," Trump told Fox News in a phone interview.
Trump, meanwhile, said he expected victory in all the key states that will decide the election, but said he would not "play games" by declaring his win too early.
"We think we are winning Texas very big. We think we are winning Florida very big. We think we are winning Arizona very big," he said.
"I think we are going to do very well in North Carolina. I think we are going to do well in Pennsylvania. We think we are doing very well everywhere."
Running behind in most opinion polls, Trump bashed his opponent, "biased" media and the "extreme" left as he repeated his argument for reelection to four more years in the White House.
"Joe Biden is not prime time," he said.
Trump called it "terrible" and "dangerous" that millions of votes mailed in might still not be counted on Wednesday.
But he downplayed allegations that he planned to prematurely declare victory Tuesday evening before enough of the vote is tallied to determine the winner.
"I think we'll have victory, but only when there's victory," he said.
"There's no reason to play games."
