Darline Graham, Ralph Norman go head-to-head in South Carolina's GOP Senate runoff

U.S. Senator Darline Graham and U.S. Rep. Ralph Norman are competing in a special Republican primary runoff election in South Carolina. Voters head to the polls on Tuesday to decide between the two candidates.

The runoff election takes place to determine who will permanently replace the late Lindsey Graham in the United States Senate, following his sudden death one month prior. The contest follows a two-week runoff window initiated after the initial primary results.
