Trump, a former reality TV star who had never previously run for public office, began his last day of campaigning in Sarasota, Florida, where he and Clinton have been locked in a tough battle in a state with a large Hispanic-American voting population.

Trump gave no ground to Clinton or to polls showing her with a narrow lead. Predicting he would win, he told supporters in Sarasota that Clinton "is such a phony" and, "We're tired of being led by stupid people."

Trump also had stops in North Carolina, Pennsylvania, New Hampshire and Michigan, closing with a late-night rally in Grand Rapids, Michigan.

Clinton was to make two stops in Pennsylvania and visit Michigan before wrapping up with a midnight rally in Raleigh, North Carolina. Her day includes an evening event in Philadelphia with Obama, first lady Michelle Obama and rock star Bruce Springsteen.

Speaking briefly to reporters in Pittsburgh, Clinton pressed her commitment to bringing the country together.

"I think that these splits, these divides that have been not only exposed but exacerbated by the campaign on the other side are ones that we really do have to ... bring the country together," Clinton said.
