Darline Graham is trying to distinguish herself from her war-hawk brother as she courts MAGA votes in a difficult GOP primary. Darline Graham has positioned herself as a staunch Trump loyalist like her brother, the late Sen. Lindsey Graham of South Carolina. “Lindsey was focused on national security, and I know that’s important, but I will probably be focused more on affordability and what matters to families in South Carolina, struggling families,” she said. President Trump's endorsement might not be enough to secure Darline Graham the nomination. “I definitely want to get that across the finish line, because it was extremely important to Lindsey,” she said.
