South Carolina GOP voters cared more about Trump’s endorsement than the interim senator’s gaffe.

Trump’s dream of sticking the MAGA-compliant sister of the late Lindsey Graham in her brother’s Senate seat may be hitting the skids.

Sen. Darline Graham Nordone secured most of the vote during a special election, but neither candidate secured over 50%, forcing a runoff.
