With only one full day between now and election day, President Donald Trump made a stop in Georgia to rally his base behind Republican candidate and Secretary of State Brian Kemp.

Appearing before thousands in an overflowing aircraft hangar in Macon, Georgia for a "Make American Great Again Rally," Trump declared, "There's electricity in the air like I haven't seen since '16."

"This is a very important election," he added. "I wouldn't say it's as important as '16, but it's right up there."

Tens of thousands more people stood outside the Middle Georgia Regional Airport, as a jumbotron televised the rally for the overflow crowd.  

People in the crowd came from North Georgia to Alabama and drove hours to see the Commander in Chief. 

"I'm really proud of our president for taking the initiative to help us win our country back," one supporter said. 

The president praised Kemp, calling him a "strong man" and "strong personality" and said he would make a great governor.

In return, Kemp said he was glad Trump "had Georgia on [his] mind."

Kemp thanked the president for his early support, saying that his endorsement in the primary was "huge" and "made a big difference." 

"I wanna thank our president for fighting for our country and hard working Georgians," Kemp said.

The president's closing argument to voters was on stark display Sunday as he sought to motivate complacent Republican voters to the polls by stoking fears about the prospects of Democratic control.

"You want to see Georgia prosperity end?" Trump told the rally crowd in Macon, Georgia. "Vote for the Democrat." Trump's remarks included ominous references to the "Antifa" far-left-leaning militant groups and a migrant caravan marching toward the U.S.-Mexico border that he has called an "invasion."

Trump criticized Democratic gubernatorial candidate Stacey Abrams, saying she would make Georgia "unsafe."

"Stacey Abrams wants to turn your wonderful state into a giant sanctuary city for criminal aliens, putting innocent Georgia families at the mercy of hardened criminals and predators," he said. "Abrams voted in favor of allowing illegal aliens to receive public benefits.  Oh, that's wonderful."

Trump was joined by former University of Georgia football coach Vincent Dooley, who thanked the president for keeping his promises.

Trump's visit comes at the end of busy week of rallies for both Kemp and Abrams. On Thursday, media mogul Oprah Winfrey was in Cobb County stumping for Abrams, while Vice President Mike Pence appeared with Kemp at three rallies around the state. Barack Obama made a speech at Morehouse University in Atlanta.
