Washington Examiner chief political correspondent Byron York said South Carolina’s Republican Senate primary is hard to predict, noting President Donald Trump‘s endorsement of Sen. Darline Graham Nordone (R-SC) may not carry the weight it once did. “It’s all happened so quickly after the death of Senator Lindsey Graham, you really haven’t had a long race where you can kind of project where the candidates are,” York said on Fox Business’s Kudlow Monday. York weighed in on the special election triggered to replace the late Sen. Lindsey Graham (R-SC). His sister, Graham Nordone, was appointed to temporarily fill the seat and entered the Republican primary, along with other GOP contenders, including Reps. Ralph Norman (R-SC) and Russell Fry (R-SC), former Gov. Mark Sanford, and businessman Mark Lynch.
