President Donald Trump is headed to Pennsylvania on Monday night to rally supporters in a state he needs to keep in his pocket in order to win a second term. Local press in Montoursville and Williamsport, the home of the annual Little League World Series, predicted a crowd of 10,000 people would come for his 58th rally as president. Some stood in line at daybreak. 'A lot of people are outside as you probably know. Many, many people,' Trump told reporters as he left the White House, 'and it's going to be a packed house as it always is.' 'I don't know if you've ever seen a vacant seat for Trump,' he said, 'but I don't think so. We're going to have a good time.' The president is blitzing into central Pennsylvania as a legal and constitutional storm swirls around his presidency in Washington. President Donald Trump headed to central Pennsylvania on Monday night for a 'Make America Great Again' rally and predicted a massive crowd People waited outside in line for hours to get in to the Williamsport Regional Airport before Trump's rally Trump supporters indulged in a tailgate-like atmosphere, complete with signs deriding the hated 'fake news' press that Trump loves to hate House Democrats hours earlier won an early round in their legal battle to get Trump's financial records from his longtime accounting firm. And the Justice Department had thumbed its nose at the president's congressional antagonists, refusing to let former White House Counsel Don McGahn testify on Capitol Hill. But in Lycoming County, Pennsylvania – Trump Country, U.S.A. – the crowd was warmed up and waiting. Trump won the county by a 70-25 margin over Hillary Clinton in 2016, one of the most lopsided results in the swing state. Barack Obama won Pennsylvania in 2012 by 5.4 percentage points over Republican Mitt Romney, now a U.S. senator from Utah. But Trump cruised to victory in 57 of the state's 67 counties, winning 20 Electoral College votes by a total of barely 54,000 votes – a 0.7 percentage point margin. Trump's trip also comes on the eve of a special election in Pennsylvania's 12th congressional district, with Republican Fred Keller facing off against Democrat Marc Friedenberg. 'Pennsylvania is Trump country,' Kimberly Guilfoyle told Monday night's crowd, half inside and half outside of an airport hangar. Guilfoyle is Donald Trump Jr.'s girlfriend, a former Fox News Channel co-host and a current Trump 2020 campaign senior adviser. Hearing a chant of 'USA! USA!' Trump Jr. joked: 'Imagine chanting 'USA' at a Democrat rally? They'd throw you out on your a**.' The president told reporters at the White House that he's optimistic he'll win Pennsylvania in 2020: 'The polls had us losing Pennsylvania last time and we won. And I expect we’ll win it this time' Trump Jr. brought his usual red meat routine, waxing on an us-versus-them theme about how Democrats in the White House would put the nation in great peril. 'They have lost their way and they have lost their minds,' the president's eldest son claimed. 'Do you want freedom or do you want communism?' he asked. 'That's what they're pushing at this point. They don't even hide it anymore.' 'You've got a lot to lose,' he said later. 'It's communism versus freedom. We're Americans! I don't think we're into that crap!' Rehashing the GOP's collective victory lap over a special counsel report that debunked earlier claims of 2016 campaign collusion with Russia, he mocked Democrats for once viewing Robert Mueller as 'the second coming of Christ.' 'Not that they believe in Christ,' he told the faithful, 'but you understand what I mean, because you do.' Lou Barletta, a former Pennsylvania congressman who ran unsuccessfully for U.S. Senate in 2016 but couldn't capitalize on the Trump wave, spoke before Trump Jr.. Donald Trump Jr., wound up his father's crowd Monday night with a red-meat routine Make America Great Again hats ahead of a President Donald Trump campaign rally in Montoursville, Pa. Speaking about a job boom that has revitalized sections of Pennsylvania, he mocked Obama for once dismissing the idea that a president could bring lost blue-collar jobs back to the U.S. without a 'magic wand.' 'Abracadabra, Mr. President. Abracadabra!' Barletta exclaimed. Minutes later Trump Jr. joked: 'You stole my Abracadabra line, Lou. I'm going to sue your a** for plagiarism!' Emergency responders were called into the standing audience twice while he spoke, to attend to people who collapsed on a hot but not sweltering evening. After thanking police and medics, he jabbed that they were a 'group of people that Democrats aren't exactly in favor of.' After the second emergency, he quipped: 'Am I that good or that bad?'All rights reserved for this news site dailymail and under his responsibility
