PHILADELPHIA/GRAND RAPIDS, Michigan (Reuters) - Donald Trump and Kamala Harris both predicted victory as they campaigned across Pennsylvania and other battleground states on Monday in the final, frantic day of an exceptionally close U.S. presidential election.
The campaign has seen head-spinning twists: two assassination attempts and a felony conviction for Republican former President Trump, and Democratic Vice President Harris' surprise elevation to the top of the ticket after President Joe Biden, 81, dropped his reelection bid under pressure from his own party. More than $2.6 billion has been spent to sway voters' minds since March, according to AdImpact, an analytics firm.
Nevertheless, opinion polls show Trump, 78, and Harris, 60, virtually even. The winner may not be known for days after Tuesday's vote, though Trump has already signaled that he will attempt to fight any defeat, as he did in 2020.
Both candidates converged on Pennsylvania on Monday to urge supporters who have not yet cast their ballots to show up on Election Day. The state offers the largest share of votes in the Electoral College of any of the seven battleground states expected to determine the outcome.
Trump campaigned in North Carolina, Pennsylvania and Michigan on the final full day of the campaign and was due to return to his home in Palm Beach, Florida, to vote and await election results.
Harris scheduled five campaign stops in Pennsylvania, including two cities where Trump also visited, Reading and Pittsburgh.
She ended the day in Philadelphia with a star-studded event at the "Rocky steps" of the Philadelphia Museum of Art, the site of a famous scene from the movie "Rocky."
