"If we win Florida it's a wrap," Obama told the audience gathered outside in Osceola County Stadium. "If we win Florida, it's over, so we've got to work our hearts out this week, these next two days, as if our future depends on it, because our future depends on it."
"They had so little confidence in his self-control, they said we're just going to take away your Twitter," Obama told the crowd. "Now if somebody can't handle a Twitter account, they can't handle the nuclear code. If somebody starts tweeting at 3 a.m. because 'SNL' made fun of him, then you can't handle the nuclear code."
The president also took issue with Trump for misrepresenting how he handled a Trump supporter who interrupted a speech he was giving last week in Fayetteville, North Carolina, saying it is an example of why Trump is uniquely unqualified to be president.
"Just a few hours later, Trump gets up on stage in front of his crowd. This was just a few hours later and he said 'Did you see how President Obama yelled at a Trump supporter in his audience?'" Obama said. "Just made it up! Didn't just make it up but said the exact opposite of what had happened -- with impunity. There was tape -- there was a video and some of the press called him out on it. But the point is that he thought it was OK just to lie in front of all his supporters -- on television."
At the North Carolina rally, the president told the crowd not to boo the protester and to respect his right to free speech. But Trump told a rally later that day that the president was "screaming at this protester" and called it a disgrace.
The president went on to make his case for Clinton, closing his remarks with a refrain from his own campaign lexicon.
"Choose hope, choose hope, choose hope, vote, elect Hillary Clinton," Obama told the crowd.
