President Donald Trump says the first step toward keeping Darline Graham as a U.S. senator from South Carolina involves helping her win a Republican runoff next week. The Republican president also begged supporters to pretend he's on the ballot Tuesday. Trump was nodding to the reality that Republican base voters lose interest in elections when he isn't on the ballot. Trump went to Myrtle Beach on Friday to support Sen. Darline Graham, his chosen candidate to succeed her late brother, Sen. Lindsey Graham. She is serving out the remainder of her brother's term. She faces Rep. Ralph Norman in Tuesday's runoff.
