From Atlanta, Georgia -

On the eve of an eleven state primary and caucus showdown for the Republican nomination, Donald Trump sparred again with Marco Rubio, implored voters to turn out on Tuesday, and rolled out a series of endorsements that might be near and dear to the hearts of many voters in the south.

"This is a great man," said NASCAR driver Chase Elliot, who joined his father in publicly endorsing Trump at a rally in Valdosta, Georgia.

"We need a change guys, that's all there is too it," said Bill Elliot. "And I think this is the man for the job."

"I love NASCAR," said Trump to cheers.

"If the people that like NASCAR vote for Donald Trump, they can cancel the election right now," Trump said with a big smile.

"I've known Donald for over 20 years," said NASCAR CEO Brian France. "You know about his winning in business and success, I'm here to tell you he wins with his family."

Trump also got down to the business of the day, urging those at his final pre-Super Tuesday rally to get to the polls.

"Go out and vote!" Trump urged the thousands at his evening rally.

With new polls out showing big numbers for Trump nationwide, the GOP front runner was excited to read the results to those in attendance and take a few jabs as well.

Trump referred several times to "lightweight Marco Rubio," who earlier in the day had said a vote for Trump was equal to a vote for Hillary Clinton.

But Trump shied away from most of the negative attacks that have been featured in recent days, as he urged his supporters to get to the polls on Tuesday.

"Tomorrow is a really big day; we have to get out and vote," Trump said, saying what he's witnessing as a candidate is a movement.

"This isn't about me, it's about you, it's about all of us," said Trump. "I'm just a messenger."

And it's possible that on Tuesday, his backers may deliver a resounding message at the polls.
