Former Massachusetts Gov. Mitt Romney, a 2008 Republican presidential candidate, is in South Carolina campaigning with Republican gubernatorial nominee Nikki Haley.
Romney, thought to be among the Republicans who will seek the party's presidential nomination for 2012, will appear with Haley in Summerville and in Bamberg, Haley's native city.
Haley is battling Democrat Vincent Sheheen and Green and United Citizens parties candidate Morgan Reeves to become the state's next governor.
Haley has led in every public poll so far.
