(CNN) It's Election Day in the Peach State once again.
Democratic Sen. Raphael Warnock and Republican Herschel Walker are facing off in Georgia's Senate runoff election. No candidate won more than 50% of the vote in the general election in November, with Warnock leading with 49.4% of the vote, Walker carrying 48.5% and Libertarian candidate Chase Oliver winning 2.1%.
Democrats already control the Senate with 50 senators plus Vice President Kamala Harris' tie-breaking vote, but the stakes remain high, with Democrats seeking to win a majority outright and Republicans looking to flip back a key seat in increasingly purple Georgia.
