South Carolina GOP tests Trump sway in governor, Senate primaries
What's next: The governor's race could move to a June 23 runoff if Pamela Evette fails to win outright.
South Carolina voters headed to the polls Tuesday in Republican primaries that will shape the races for governor and U.S. Senate, with President Donald Trump's influence hanging over both contests. In the governor's race, Trump backed Lt. Gov. Pamela Evette against U.S. Rep. Nancy Mace, Rep. Ralph Norman and businessman Rom Reddy. The outcome will show whether his endorsement can deliver an outright win or force a runoff later this month. In the Senate primary, Lindsey Graham is seeking the GOP nomination for a fifth term after securing Trump's backing before his campaign began. Democrats are trying to break a 20-year statewide losing streak in November, but Republicans remain dominant in South Carolina.
