US state Georgia's voters are set to decide the final US Senate contest of the midterm elections, choosing between the incumbent, Democrat Raphael Warnock, and a Republican football legend, Herschel Walker.
Neither candidate won more than 50% of the vote in an election in November, although Warnock had a lead just under one percent over his opponent. As a result, the two must face each other again, in a run-off vote.
Whoever wins, the Democrats will retain control of the upper chamber of Congress, as they already secured 50 of the body's 100 seats and hold the vice-president's casting vote for breaking ties.
However, a Democratic victory could give them more breathing space in Senate votes. It would also serve as an encouraging sign for the party in the 2024 presidential election.
