Georgia Senate runoff updates: 2M already voted; polls close 7 pm ET - USA TODAY

Georgia voters are once again left with the final say in how Congress will look as the nation watches the Senate runoff race between Democratic incumbent Raphael Warnock and Republican challenger Herschel Walker. .

Democrats have already secured the upper chamber's majority with victories in other states, but that doesn't mean nothing is at stake Tuesday.

For starters, Georgia's special election will determine whether the chamber remains evenly split at 50-50, which proved to be a difficult tightrope for President Joe Biden and the Democrats.
