Trump's 2020 kickoff features media bashing and attacks on Joe Biden and old ...

Donald Trump's first official campaign rally of 2020 opened up much the way his 2016 candidacy ended - with his audience chanting 'Lock her Up!' in a slam on former Democratic opponent Hillary Clinton.

The president's daughter-in-law, Lara Trump, invited the criticism when she wound up an arena of supporters.

She said days before the election, the media was saying that Hillary Clinton was going to be the 45th President of the United States. 'They have always been wrong,' she said. 

Attacks on the media as 'fake news' and 'dishonest' from Lara and her husband Eric, who spoke after her, had a crowd of more than 20,000 screaming, 'CNN Sucks!'

'We're going to fight like hell. Our family is going to fight like hell for this country,' Eric Trump said. 'And we will never stop fighting, and we will never stop winning.' 

Donald Trump Jr.  mocked Joe Biden before the rowdy crowd that waited in the heat and rain for hours.

'He gets up on the stump. It's so stupid,' he said, claiming the ex-VP has four-person crowds. 

The president's son said he agrees that government is broken and it's a problem. 'The problem is Joe, you've been in government for almost 50 years.'

Trump warned the public that this official launch of 2020 campaign will be 'wild,' after supporters camped out in tents for more than 30 hours to save their places at the front of a massive line that would ensure them floor seats at Tuesday evening's show, and his children suggested their father would deliver.

Don Jr. mocked Biden's pledge to cure cancer with his moonshoot project. 'Why the hell didn't you do that over the last 50 years, Joe?' he asked.

Saundra Kiczenski, a Michigan native who works in retail, waited from 7 am on Monday. She said she'd been to rallies in support of the president in 15 states. She spent Monday night on the pavement in a sleeping bag. 

'I took the hotel pillow and slept on the ground,' she told DailyMail.com on Tuesday afternoon as she waited to get in. 

The Republican incumbent set the tone for the monster rally in Florida he'd be appearing at in the evening in a morning tweet that bashed the media and compared the scene outside the Amway Center to a rock tour.

'The Fake News doesn’t report it, but Republican enthusiasm is at an all time high. Look what is going on in Orlando, Florida, right now! People have never seen anything like it (unless you play a guitar). Going to be wild - See you later!' he tweeted on Tuesday am. 

Trump had apparently dropped a claim that 'thousands' turned up on Monday, with about 250 people camping overnight. But the numbers grew steadily as temperatures and humidity soared in Orlando. 

A cover band with aging rockers who call themselves 'The Guzzlers' revved up the crowd under a beating sun at a 'festival' the campaign held in an outdoor parking lot, where vendors sold a captive and cramped group sodas, snow cones and Trump umbrellas.  

Sweltering heat that topped 87 degrees soon turned to pouring rain, giving the umbrellas a dual purpose for supporters like Richard Snowden who chose to remain.

A resident of Las Vegas, Nevada, Snowden said he'd be 'remiss' to have skipped the kickoff. He told DailyMail.com from the comfort of a party-style tent his group had pitched that he'd attended 54 rallies since Trump announced his candidacy for office in 2015. 

The mantra when its rains pours came into play as a new Quinnipiac poll showed Trump losing Florida to Democratic nemesis Joe Biden was released midday. The former vice president would beat Trump by nine points, 50 – 41 percent, the newly-released survey showed.

Vermont Sen. Bernie Sanders would win by a similar margin, 48 – 42, while other top Democrats would perform in the poll's margin of error. 

Trump campaign manager Brad Parscale told DailyMail.com inside the rally that Quinnipiac is 'c**p' in response to the latest poll showing bad news in a critical swing state for the controversial president. 

The campaign at-large also tried to brush off bad national and state-based polls that showed Biden whooping Trump in Tuesday's lead up.

But even Snowden Trump supporter called himself a pragmatist and said the president's reelection odds, 'I don't think it's going to be a cakewalk.'

'The incumbency will help. He won't catch them flat-footed this time,' he observed.  '

Trump's campaign is turning the area outside the arena that can seat 20,000 people into a festival-like atmosphere with music and food trucks to help supporters pass the time. 

The most coveted positions are not seats at all - they're standing positions near the front of the stage. Backers of the president in that area are likely to get a handshake, a selfie or Trump's autograph at the event that formally marks the beginning of his campaign for a second term.

The city's mayor, Buddy Dyer, also turned up, despite being a Democrat, to speak to security personnel at the site.

The welcome from the local newspaper was less warm, however; the Orlando Sentinel used the campaign launch to endorse 'Not Donald Trump,' saying: 'After 2 1/2 years we've seen enough. Enough of the chaos, the division, the schoolyard insults, the self-aggrandizement, the corruption, and especially the lies.'

That was hardly likely to blunt Trump's conviction that the rally will be a suitable kick-off to his campaign. 

All of Trump's children and his wife Melania will be with him at the event, sources told DailyMail.com, as will the Mike Pence, the president's running mate and the nation's vice president. 

It will be 13-year-old Barron Trump's first appearance at a campaign rally since his father took office. Trump's youngest daughter Tiffany, who has not typically treated politics like a family affair, will also be there.
