"I am running for Governor because I feel like I must do all that I can to fight for the people of South Carolina," Smith said. "I am running because I want South Carolina to realize her fullest potential and to do that means no one gets left behind."
Smith becomes the first Democrat to join the race.
On the Republican side, Gov. Henry McMaster is gearing up for his first run at the seat as the state's chief officer. McMaster faces former DHEC head Catherine Templeton, former Lt. Gov. Yancey McGill, and current Lt. Gov. Kevin Bryant.
