President Barack Obama campaigned for Hillary Clinton and other Democrats in Florida election races in Kissimmee Sunday, encouraging voters to "choose hope" and saying the choice for president in this election "could not be simpler or clearer."

As with other Hillary Clinton surrogates criss-crossing the state this weekend, Obama had some celebrity star power on stage to warm up the crowd before he spoke. Music legend Stevie Wonder performed for the audience at the Osceola County Stadium prior to the president's remarks.

When Obama took the stage, he thanked Wonder and joked that he almost came up on stage to sing with him.

"I was going to come up and sing with Stevie," said Obama. "But Stevie explained that this was designed to get votes, so that was a bad idea."

All kidding aside, the president once again made his case for the importance of getting out to vote, couching it as a choice to defend progress made since 2008.

"I need your help to help finish what we started eight years ago," said Obama. "No wonder I've got grey hair -- we've been working hard."

He also made clear his thoughts on what was at stake come Election Day, and just how important a role Florida will play when the votes are counted.

"All the progress we've made goes out the window if we don't win this election," said Obama. "And we win this election if we win Florida."

Obama described the choice between the contenders for the Oval Office as a choice that "could not be simpler or clearer."

"On the one hand, you have somebody who may be the most qualified person ever to run for the presidency," said Obama. "On the other, you have 'The Donald."

As has been his practice at appearances on the campaign trail, when the crowd booed at the mention of Donald Trump or Republicans, Obama corrected them, saying don't boo -- vote.

"[Trump] can't hear your boos," said Obama, "but he can hear your vote."

In talking up Clinton to the crowd, Obama pointed to her intelligence and her steadiness. He also highlighted her work ethic and temperament as a contrast to her opponent.

"When things don't go her way, she doesn't whine," said Obama. "She doesn't complain, she doesn't talk things being rigged. She just works harder."

This is the president's second visit to Central Florida in just a little more than a week.    

On Oct. 28, he visited the University of Central Florida where thousands of people showed up to hear him speak. During his speech, the president encouraged people to vote for Clinton—telling voters they have the chance to "shape history." 

Most recently, the president was in North Carolina where he spoke at a Hillary Clinton rally. He talked about Donald Trump and what he said is violent rhetoric coming from his supporters.

"They've become so accustomed to saying these things in their rallies and their town halls and on the Internet, it becomes an applause line. And it's become normalized. The idea of making a joke about violence against somebody who's running for president, or is president. There's a reason why we've got Secret Service. There's nothing normal about that," said Obama.
