In 2016, Trump surprised America and the world by winning the United States presidency, as most political analysts expected long-known candidate Hillary Clinton to win. "If you look at the overall speech, he covered the economy, immigration, judicial appointments, national defense, national security - it was a pretty broad ranging speech".
But those involved in the president's reelection effort believe that his brash version of populism, combined with his mantra to "Drain the Swamp, " still resonates, despite his administration's cozy ties with lobbyists and corporations and the Trump family's apparent efforts to profit off the presidency.
"Not acceptable. It's not going to happen".
Trump - himself accused by opponents of wide-ranging corruption - told the crowd that together they had formed "a great political movement" that had "stared down a broken and corrupt political establishment".
Trump's campaign team had it all planned a long time ago, as trademark for the new slogan was registered on 18 January, 2017, two days before Trump was sworn into office, and 882 days before the Orlando rally, according to an application published by Yello's Hunter Schwarz.
"This is a historic event, we would not miss this for anything", one fan, David Meloney, said.
And ahead of the rally, he pushed several of the core issues in his populist, nationalist platform.
Trump tried to make the case that he had made good on his 2016 promises, including cracking down on illegal immigration and boosting jobs.
This is a theme he has hammered repeatedly during his presidency and he is ramping this up further with an announcement on Tuesday on Twitter that he wants the deportation of "millions of illegal aliens".
"You remember during one of the debates when "Crooked Hillary" said 'If I win, are you going to support me?' But I must be honest, I didn't give her a great answer", Trump said, using the former Secretary of State's voice. "After 2½ years we've seen enough".
But there's no question that a lengthy probe into Trump's murky dealings with Russian Federation and his divisive, bruising style have left him wounded.
The board clarified that this non-endorsement isn't necessarily a Democratic endorsement by default and that it would be open to endorsing an unlikely Romney or John Kasich campaign should they defeat Trump in the GOP primaries.
They spent Tuesday braving downpours and listening to a cover band playing Southern rock standards such as Lynyrd Skynyrd's "Sweet Home Alabama" as they waited for Trump's arrival. If anything, the surveys point to another bitterly fought, tight race.
