Donald Trump predicted victory Monday in Wisconsin, upping the ante from previous statement in which he stopped short of saying he would beat Texas Sen. Ted Cruz in Tuesday's Republican primary.

'I really believe tomorrow we're going to have a very, very big victory,' he said during an event billed as a town hall in the Mississippi River town of La Crosse.

'I've been up here a lot, and I love it. And the people I love. I have many friends from Wisconsin but they told me this was going to happen.'

'I think I'm going to have a big Democrat crossover, and I hope I do,' he said, predicting that independents will also come out in droves to support him.

UNDERDOG? Donald Trump predicted a 'very, very big victory' in Wisconsin, defying conventional wisdom and opinion polls to forecast an upset over Ted Cruz

CONFIDENT: Polls show Cruz up between 6 and 10 percentage points but those surveys don't measure Democratic crossover voters who might flock to Trump

'I DON'T EXAGGERATE': Trump, who has embraced hyperbole more than any presidential candidate in recent memory, insisted Monday that he's 'learned' to shoot straight

Wisconsin's GOP primary is open to all Wisconsinites, not just registered Republicans.

While polls show Cruz leading, those numbers don't include Democrats who might flock to Trump's populist message.

DailyMail.com spoke to a random sample of 35 people who stood in line Monday morning in La Crosse and said they were not yet certain who they would vote for on Tuesday.

Of that group, seven said they were teetering not between Trump and Cruz, but between Trump and Bernie Sanders, the Democratic socialist who has turned the Democratic primary upside down.

Trump never took questions on Monday morning, turning the town hall into a stump speech delivered to a few thousand people who stayed on their feet for nearly an hour.

The billionaire will hold an airport-hangar rally in the northwest corner of the Badger State before ending the night in Milwaukee.

He said his wife Melania is flying in to appear with him there. She's also bringing a souvenir with her – a congratulatory plaque Wisconsin Gov. Scott Walker once presented the billionaire as a token of thanks for an unspecified political gesture.

Trump joked last week that he would have to dig it out from under a pile of similar plaques. Walker is touring the state with Cruz, whom he endorsed just days ago.

'I got a plaque from Walker saying this or that,' Trump said Monday. 'We're going to have a lot of fun. I'm going to show the plaque.'

CHEESEHEADS FOR DONALD: Wisconsin's primary election will be held on Tuesday in the state known for its cheese and its Green Bay Packers

The real estate tycoon and reality TV star said that if he can win a surprise victory in Wisconsin's primary, 'the end will be here.' That was a reference to his plodding path toward securing 1,237 Republican National Convention delegates, the slimmest majority that might cinch the nomination.

But 'it may not happen because we have the [party] machine against us,' he conceded.

'I want to get there with Wisconsin,' he said. 'This will send such a signal that the people of our country are so sick and tired of incompetent representation.'

At that line, a woman in the back of the room – the only protester to raise a voice Monday morning – yelled, 'Like Donald Trump!'

'You talk about yourself!' she blared as she walked out without the police escort that typically ushers out dissenters.

Trump has lately shown more self-awareness than in previous months, saying over the weekend that he made a mistake in retweeting an unflattering picture of Cruz's wife.

But Monday's introspection was of a different sort.

'I don't exaggerate. I have very little exaggeration. I've learned,' he told the crowd, defending his claim that he has collected 'millions and millions more votes' than Cruz in the statewide primaries and caucuses held to date.

Moments later, in the midst of his stump material about American manufacturers that send jobs offshore, he said: 'They're firing thousands and thousands – and millions of people!'

Trump also repeated his pledge to moderate his tone if he sends Cruz and Ohio Gov. John Kasich packing the way he has 14 other rivals.

'I can be the most presidential person you've ever seen,' he said.

'I mean, I'm a very smart person ... I'm so much smarter than the people who write the stories.'

Kasich, he said, had no business continuing his quixotic quest for the White House since he has only won his home state and his only hope is a come-from-behind shocker in a contested convention.

'He's one-and-thirty. He really should get the hell out,' Trump boomed.

He also complained about the wall-to-wall TV ads lobbing rhetorical grenades at him in Wisconsin, saying he was bombarded by them in his Wisconsin hotel room on Sunday night.

Trump didn't say where he laid his head but hinted at his lodging priorities.

'All I want is clean. It has to be clean,' the noted germophobe said.
