The four Republicans who want to become South Carolina's last elected lieutenant governor are scheduled to debate in Columbia.
The debate is set for 7 p.m. Thursday and will be carried live by South Carolina Educational Television. It will include all four candidates - Mike Campbell, the son of former Gov. Carroll Campbell, retired Kiawah Island developer Pat McKinney, former state attorney general Henry McMaster and retired Army chaplain Ray Moore.
All four vow to help Gov. Nikki Haley. This is the last year South Carolina voters will choose a lieutenant governor. Starting in 2018, candidates for governor will choose who they want as their lieutenant governor and run on the same ticket.
The winner of Tuesday's Republican primary will face Democratic state Rep. Bakari Sellers in the fall.
