Representative Mike Collins trails Senator Jon Ossoff in public polling ahead of the Georgia Senate race.
The two candidates met Tuesday for their second and final debate of the campaign.
Collins took a more aggressive approach than in their first meeting, directly challenging Ossoff throughout the night.
The debate marked the last scheduled face-to-face encounter before voters cast their ballots.
Ossoff, the incumbent, defended his record while Collins pressed attacks on key policy areas.
Polling averages show Ossoff holding a lead, giving Collins little room for error in the final stretch.
Both candidates used the platform to sharpen their closing messages for undecided voters.
The Georgia race remains one of the most closely watched Senate contests in the country.
Early voting and turnout operations now take center stage as the campaigns enter their final phase.
