RALEIGH, N.C. — Donald Trump said Monday that enthusiasm for him and anger with the political establishment will deliver a victory that stuns his critics, as the Republican presidential nominee traveled to five states the day before Election Day.

"This is it folks," Trump told a screaming crowd in Sarasota, Fla., a state he needs to carry Tuesday.

"We will never have another opportunity," the insurgent Republican candidate told his followers, urging them to turn out the vote: "Good luck! Get out there!"

After the Florida event, Trump headed to other states that may be essential to his hopes of an Electoral College win: North Carolina, Pennsylvania, New Hampshire and Michigan. He predicted success in each place and claimed that "my poll numbers are going through the roof," though most surveys give Clinton the edge in the election overall.

Trump's campaigning may not end Monday: Aides said he is planning one last fly-around on Election Day itself.

The GOP nominee enters the final days amid news that the FBI, even after reviewing new material, has closed its investigation into Clinton's use of private email during her years in the State Department, a decision the Republican candidate is blasting.

Trump — who had praised the FBI for announcing it would review the case late last month — said Monday that Clinton is being protected by a "totally rigged" system, and "should not even be allowed to run for the presidency" at all.

"What's happening is a disgrace," Trump said in Sarasota, later calling Clinton "a phony."

Earlier, during a post-midnight rally in Leesburg, Va., Trump said: "Hillary Clinton is guilty — she knows it — the FBI knows it."

While polls nationally and in key battleground states give Clinton a slight lead, Trump predicted a win that will surprise the elites who disdain his candidacy. Touting the big crowds at his rallies and their enthusiasm, Trump and aides say he has a "hidden vote" of people who won't acknowledge their support to pollsters. He predicts an outcome similar to that of the Brexit vote, referring to the United Kingdom's surprise decision to leave the European Union.

"We are going to have one of the great victories of all time — of all time," Trump said in Virginia. "This is going to be Brexit times 50."

In addition to Republican-leaning states, Trump probably needs to win a few that have gone Democratic in recent elections: Hence the trips to Pennsylvania and Michigan (as well as Minnesota on Sunday).

Predicting an Election Day surprise for political elites, Trump told supporters in Michigan during a campaign marathon on Sunday that "they're getting a little concerned. ... This wasn't the way it was supposed to be."

The Trump campaign also continued to raise money. A late fundraising email read: "We are on the doorstep of a HUGE victory and new direction for our country ... but we must close strong, and I need EVERY supporter on board."

In Florida Monday, Trump bantered with the crowd, one of whom handed him a Halloween mask of his head, complete with orange bouffant.

"Looks just like me," Trump said. "Nice head of hair, I'll say that."

The flurry of last-minute stumping ends one of the most unique candidacies in presidential history — and one of the most volatile.

Since announcing his White House bid in June 2015, Trump has tapped into strong anti-establishment, anti-government feelings, particularly among conservative Republicans.

In speeches and on social media, Trump's caustic comments have alienated women and Hispanic voters. Critics have cited Trump's call for an anti-migration wall between the United States and Mexico and allegations from at least a dozen women that he groped or inappropriately touched them in making the case against his fitness to be president. They also note that a number of racists and anti-Semites seem attracted to Trump's campaign.

Meanwhile, Trump fired up his base — and rolled to the Republican presidential nomination — with his calls for a border wall, his support of at least a partial ban on Muslim entry into the United States and his bracing attacks on "Crooked Hillary Clinton." The New York businessman says the government has betrayed American workers with "open borders" immigration policies and trade deals he claims have shipped U.S. industrial jobs overseas.

"We're tired of being led by stupid people," Trump said in Sarasota. "They're stupid people."

During his weekend campaign stops, Trump said Tuesday will bring something special.

"It will be so special," Trump said early Monday in Virginia. "It will be an amazing day. It will be called Brexit-plus-plus-plus."
