Darline Graham and Ralph Norman In Senate Runoff Tuesday

The winner of Tuesday's runoff will take on Dr. Annie Andrews, who won the Democratic primary in June.

The South Carolina Senate race between Darline Graham and Ralph Norman heads to runoff Tuesday.

Republicans will decide who will replace Sen. Lindsey Graham on the ballot in the November midterm election. The vote comes after his recent sudden death.

Graham’s sister, Darline, faces Norman with both getting top votes in the special primary election in early August. Darline gained nearly 33% of the votes with Norman securing almost 25%, but neither won 50% of the vote.

The winner of Tuesday’s runoff will take on Dr. Annie Andrews, who won the Democratic primary in June. Polls are open until 7pm Tuesday.
