WILMINGTON, N.C./MIAMI - Republican Donald Trump and Democrat Hillary Clinton traded barbs as they entered the last three days of campaigning in the U.S. presidential election with competing events on Saturday in Florida, a swing state that could prove decisive in Tuesday’s vote.

Clinton and Trump are making their closing arguments to American voters, crisscrossing the United States in hopes of convincing last-minute undecided voters and rallying their bases to turn out enthusiastically on Election Day.

Opinion polls show Clinton still holds advantages in states that could be critical in deciding the election, but her lead has narrowed after a revelation a week ago that the Federal Bureau of Investigation was looking into a new trove of emails as part of its probe into her handling of classified information while she was secretary of state.

A McClatchy-Marist opinion poll released on Saturday of voters nationwide showed Clinton leading by one percentage point compared to 6 percentage points in September. A Reuters/Ipsos tracking poll also released Saturday showed Clinton ahead by 4 percentage points nationally compared to 5 points on Friday.

The state opinion polls have found Florida as one of the most competitive among the battleground states - those that are hotly contested because their voters can swing either to Republicans or Democrats. The 2000 presidential election was decided in Florida after a dispute over votes and recounting of ballots went to the U.S. Supreme Court, which ruled in favor of Republican George W. Bush over Democrat Al Gore.

The Real Clear Politics average of Florida opinion polls found Clinton with a lead of about 1 percentage point - indicating the race there is a virtual tie.

Trump spoke at a rally on Saturday morning in Tampa, Florida, where he continued to criticize Clinton for supporting the Affordable Care Act, also known as Obamacare, in the wake of announcement that premiums are going to rise next year.

“It’s not going to matter because if we win I’m throwing it out anyway,” Trump said.

Shortly before Clinton took the stage in Pembroke Pines, Florida, it began raining. People in the crowd waiting for Clinton at the outdoor rally remained in place as a downpour began, taking out umbrellas and fashioning garbage bags into head coverings.

“I’m thrilled to be here and boy is this a hardy group, rain or shine you are ready,” Clinton said, her voice cracking with hoarseness.

She cut her speech short as she became soaked in rain, saying, “I don’t think I need to tell you all of the wrong things about Donald Trump.”

In North Carolina, Trump campaigned along with his wife Melania, who has been nearly invisible in the campaign after her speech at the Republican National Convention in July that had passages lifted from a previous speech by Michelle Obama. Melania Trump did deliver a speech this week in Pennsylvania.

“It is a movement for all of those who are left behind by a broken and rigged system,” Melania Trump said on Saturday of her husband’s campaign. “This is a movement which is inspiring and inclusive.”

Early voting began in September and the data firm Catalist estimates more than 30 million ballots have been cast in 38 states. There are an estimated 225.8 million eligible U.S. voters. Saturday is the final day for early voting in many Florida counties.

Trump will also campaign Saturday in Nevada and Colorado. Trump told the crowd in Tampa that there would be a campaign event in Minnesota this weekend, although one had not previously been scheduled. Minnesota has not voted for a Republican since 1984. His campaign confirmed a rally scheduled for Wisconsin on Sunday has been canceled.

Clinton started the day by stopping by the West Miami Community Center, a Cuban American neighborhood, with telenova star Jencarlos Canela, a Miami native of Cuban descent.

She then visited her campaign’s office in Little Haiti where there is a large concentration of Haitian-American residents. Clinton was joined by Sybrina Fulton, the mother of Trayvon Martin, the unarmed black teenager who was shot dead in 2012 by a Sanford, Florida neighborhood watchman, George Zimmerman.

While Trump prefers large-scale rallies, Clinton has filled her campaign schedule with targeted appearances meant to court voters in specific demographics. Cuban voters have historically favored Republicans, but younger generations have shifted toward Democratic Party candidates.

CELEBRITIES SUPPORT CLINTON

Clinton heads to Philadelphia, where she will appear with pop singer Katy Perry for an evening rally.

Clinton has leaned on her celebrity supporters to draw large crowds in the final days of the campaign. On Friday night, she appeared in Cleveland with rapper Jay-Z and singer Beyonce.

Clinton rallied millennial supporters on a conference call, urging them to vote and get others to do so too. “I really believe you will decide this election and of course I’m hoping that you will make sure everyone you know will come out and vote because America is counting on us,” Clinton said.

Trump has appeared to be struggling with support from his own Republican Party. Last week, Reuters/Ipsos polling found a majority of Republicans thought Clinton was going to win. This week, however, those numbers flipped and Republicans now narrowly believe he could win.

Fred Reilly, 55, a lawyer from Haines City, Florida, said attended Trump’s rally in Tampa and he is concerned that not enough Republicans are rallying behind Trump. He supported U.S. Senator Ted Cruz of Texas during the primary, but now backs the New York businessman who has never previously run for political office.

“I’m extremely, and you can underline extremely, disappointed with many in the Republican Party and the way they’ve handled this,” Reilly said of the party’s response to Trump.
