President Barack Obama warned that Donald Trump would have more power to act on his “twisted notions” if elected and said the Republican’s rhetoric is “no joke” during a rally in Florida on Thursday.

“Who you are, what you are, does not change after you occupy the Oval Office. All it does is magnify who you are. All it does is shed a spotlight on who you are,” Obama said.

The president listed off a number of Trump’s most controversial statements, like threatening to throw Hillary Clinton in jail and how he has used his celebrity to make unwanted advances on women.

“You will have more power to carry out the twisted notions you had before you were in office. So you can’t make excuses for this stuff. This isn’t a joke,” Obama said.

The president has lamented the “reality TV-ized” atmosphere of the campaign, telling supporters the election is not “Survivor” or “The Bachelorette.”

Trump is also campaigning in Florida on Thursday and has directed an increasing amount of attention to Obama as the commander-in-chief continues to stump for Clinton.

“Looking at Air Force One @ MIA. Why is he campaigning instead of creating jobs & fixing Obamacare? Get back to work for the American people!” Trump tweeted.

Polling shows the Sunshine State is a tossup just five days before the election. An NBC News/Wall Street Journal/Marist poll released Sunday shows Clinton earning 45 percent support and Trump with 44 percent.
