After months on the campaign trail, Democrat Kamala Harris and her Republican rival, Donald Trump, are now just one day away from Election Day, but they still have a full day of rallies before the polls open on Tuesday.

Opinion polls show the pair locked in a tight race, especially in several battleground states, with Vice President Harris bolstered by strong support among female voters while former President Trump maintains solid numbers with Latino voters, especially men.

More than 78 million Americans have already done so ahead of Tuesday's Election Day, according to the University of Florida's Election Lab, approaching half the total 160 million votes cast in 2020, in which U.S. voter turnout was the highest in more than a century.

Harris will spend the day in Pennsylvania and start the day in Scranton before delivering remarks in Allentown. Joined by her husband, First Gentlemen Doug Emhoff, she'll attend rallies and concerts in Pittsburgh and Philadelphia with Lady Gaga, Kate Perry, Ricky Martin, The Roots, and remarks by Oprah Winfrey.

Trump's final day of campaigning on Monday will include stops in three of the seven battleground states expected to determine the winner. He will visit Raleigh, North Carolina; Reading and Pittsburgh in Pennsylvania, and Grand Rapids, Michigan. He then plans to return to Palm Beach, Florida, to vote and await election results.

Minnesota Governor Tim Walz, Harris' running mate, and his wife, Gwen Walz, will travel to La Crosse, Stevens Point, and Milwaukee, Wisconsin, before heading to Detroit, Michigan, for a rally and performances by the Detroit Youth Choir, Jon Bon Jovi, and The War and Treaty.

And to end the night, the governor's interview on The Late Show with Stephen Colbert will air at 11:35 ET.

On Tuesday, the Harris-Walz campaign will host its election night event at Howard University in Washington, D.C., Harris’ alma mater.

Trump’s campaign will host an election night watch party at a convention center in West Palm Beach, Florida but has not announced the former president’s election night plans, according to the Palm Beach Post, part of the USA TODAY Florida network.
