Donald Trump implored voters in Florida on Wednesday to "get the hell out" of his campaign rally and register to vote before the Oct. 18 deadline, which a district court judge had extended earlier in the day due to the impact of Hurricane Matthew.

"Who is not registered? Is there anybody in here that is not registered?" Trump asked the audience at an event in Ocala, Fla. "If you're not registered, get the hell out of here, OK?"

"This is a nice looking young guy," Trump said, gesturing toward a young man in the crowd. "Hey listen, leave right now and go register [to vote]. They just extended it for a little while so right after, raise your right hand, do you promise you're going to register right after this?"

The Republican presidential nominee pressed his supporters further, "Seriously, I'm curious, who is not registered in this room? OK, all young people," he said after scanning the crowd.

"So go out and register and we're going to have — I'll tell you honestly we're going to have a big four years, eight years. We're going to have a big, great future for our country," Trump said, noting that his supporters could also "request an absentee ballot and you can vote by mail if necessary."

Trump's urging comes hours after Florida's Division of Elections released new data revealing that Florida Democrats had registered 60 times as many residents to vote than the state's Republican Party between Sept. 10 and the original Oct. 10 registration deadline.

Florida has become a must-win battleground state for the GOP nominee, who currently trails Hillary Clinton by 2.4 percentage points in the RealClearPolitics state-level polling average.
