Lindsey Graham's sister will face a runoff race after coming up short to serve a full term in the US Senate despite Donald Trump's endorsement. Darline Graham Nordone, 62, whose brother died suddenly last month, leaving his South Carolina seat vacant, garnered 32.56 percent of the vote in her debut political contest in a crowded field of political veterans. She will face off against Congressman Ralph Norman, who came in second place with 24.38 percent of the vote. The primary runoff election will take place on August 25. 📷 Reuters / Getty Images / AP #trump #senate #lindseygraham #politics #news
