Donald Trump spoke for an hour on Monday, uninterrupted by protesters, in a rust-belt speech that may signal a cease-fire on the part of leftist activists who have sabotaged his events in recent weeks.

Despite the presence of Youngstown State University just a 20-minute drive away, there were none of the youthful, cause-driven disruptions that have become a staple of Trump rallies.

The past 72 hours have seen fistfights, vulgar shouting matches and near riots in Ohio, Illinois and Missouri, three of the five states where primary voters will head to the polls on Tuesday.

But in an airport hangar hosting close to 10,000 people, Trump made his final appeal to Ohioans without having to compete with Black Lives Matter, MoveOn.org or advocates for illegal immigrants.

He took his message of home-grown industrial revolution to the heart of the rust belt, speaking a short drive away from disintegrating factories that once hummed with the vitality of middle America.

Lamenting the flight of industry – and its jobs – to Mexico, Trump noted that Eaton Corporation and Ford were both outsourcing work that used to be done in Ohio.

'With me – not gonna happen anymore,' he said. 'We're not gonna be the dummies anymore.'

'You're losing your jobs, you're losing your incomes, you're losing your industries!' he said, laying part of the blame at the feet of Gov. John Kasich.

And in a twist from his normal reliance on Mexico as his employment whipping boy, he pointed one figer south while another stretchedto the east.

'It's Vietnam, it's India, it's everybody!' he said.

'Kasich cannot make America great again. Can't do it,' Trump said as boos erupted at the mention of the moderate Republican's name.

Trump has frequently cited blind luck and an oil strike as the main reason for reductions in Ohio's budget deficits.

'If you didn't hit oil – that wasn't because of him, believe me – you would have had a disaster,' he said Monday night.

Trump hammered Kasich as an 'absentee' governor who never left New Hampshire during the primary season there, neglecting his responsibilities in Columbus.

'I still work. I have a job,' he boasted.

'He goes to New Hampshire, he's living there! ... He loses badly, he gets killed, I win in a landslide.'

Trump finds himself in a tighter race than anticipated for Ohio's 66 Republican National Convention delegates.

Late-breaking polls put him in a statistical dead heat with Kasich.

In one poll released Monday morning, Kasich leads him by 5 percentage points – which is still within the poll's margin of error.

In Florida the situation is dramatically different: Trump leads the pack by approximately 20 points and is expected to win in a laugher over Sunshine State sen. Marco Rubio, who has dropped into third place.

Both Ohio and Florida are so-called 'winner take all' states that will award delegates all at to a single first-place victor instead of splitting them up according to how many votes each candidate received.

Florida's 99 delegates will likely go to Trump. The other states holding Republican primaries on Tuesday are Illinois, Missouri and North Carolina.

With Florida practically in the bag, Trump's campaign decided at the last minute to invest more time in the Buckeye State, scheduling the Youngstown-area rally over the weekend and calling off an event near Miami.

'We had a change of plan,' he told his audience in Ohio as he surveyed their numbers from behind a podium.

'We set this up, what? 15 hours ago? And look -- this is the place I want to win. This is the place that's gonna do it.'

'You've gotta beat Kasich,' he told his crowd. 'He's not going to be a great president. He's not going to be strong.'

In a new twist Monday on his regular routine about his power to draw new, first-time voters to the Republican Party, Trump asked for a show of hands.

'Every twentieth person says to me, "You know, Mr. Trump, I've never, ever voted before",' he claimed.

'Who's never voted before, at this rally?' he asked.

About 200 hands went up – some reaching from youthful hoodies and others showing the signs of middle and old age.

'So many people!' Trump marveled. 'They say to me: "I never wanted to vote because I never saw somebody I wanted to vote for".'

Grinning broadly, Trump watched the hands shot up, and saw that it was good.
