Lindsey Graham’s term, many Republicans in South Carolina saw it as a fitting tribute to her late brother,” CNN reports.“But four days later, following Trump’s announcement that he wanted Graham to run for a six-year term, their feelings quickly flipped.”“The president’s decision to get behind a political unknown for a breakneck special election process is further testing his clout in South Carolina, a solidly red state where Republicans already this year have roundly rejected his first pick for the governor’s race and his push to redraw the state’s congressional maps.
