Georgia's U.S. Senate candidates are making last-minute efforts to maximize voter support as Tuesday's runoff elections draw closer.

Republican Sen. David Perdue, who is vying for re-election against Democrat Jon Ossoff, remains in quarantine after coming in close contact with a campaign staffer who tested positive for coronavirus.

But Perdue called in to "Fox & Friends" on Saturday morning -- urging Georgians to vote for him and fellow Republican incumbent Sen. Kelly Loeffler, who faces a challenge from Rev. Raphael Warnock, a Democrat. 

"Kelly Loeffler and I will get this vote out on Tuesday, and we'll save America. That's what this is about. This is the last line of defense from this radical socialist agenda," Perdue said.

Loeffler has several events scheduled for Sunday, including a get-out-the-vote event in McDonough, Georgia, with South Dakota Gov. Kristi Noem, a newly emerged favorite among Republicans.

 Loeffler will also be in Cartersville, Ga., and Canton, Ga., on Sunday.

Meanwhile, Ossoff and Warnock will hold a drive-in rally with Vice President-elect Kamala Harris on Sunday.
