(CNN) - Mitt Romney was in South Carolina Thursday to campaign for Republican gubernatorial candidate Nikki Haley.
The former Republican presidential candidate endorsed Haley and donated $42,000 to her campaign earlier this year.
The campaign for Haley's Democratic opponent, Vincent Sheheen was critical of the Romney visit because of the health care law enacted when Romney was governor of Massachusetts.
"Nikki Haley has spent months misleading the voters on Vincent Sheheen's position on mandated healthcare, but brings in the father of mandated health care to campaign with her," Kristin Cobb, Sheheen's communications director said in a statement.
Thursday's visit is the latest stop for Romney who has spent the election season traveling across the country supporting Republican candidates. On Friday he will appear in New Hampshire at rallies for gubernatorial candidate John Stephen and Congressional candidates Charlie Bass and Frank Giunta. Monday he will stump in Rhode Island for John Loughlin, who is running for Congress.
Romney has continued his national presence since his unsuccessful run for president in 2008, and all evidence points to him running for president again in 2012.
