(CNN) - Jenny Sanford is re-affirming her support for Nikki Haley in the South Carolina governor's race, a day after the Indian-American candidate was called a "raghead" by a political foe.
"I have watched with revulsion the spectacle that is now surrounding the Governor's race," Sanford said in a statement Friday. "Our state is better than this."
Haley has also denied multiple claims of infidelity over the last two weeks, accusations she says are being pushed by rival campaigns.
"I can't help but think that these attacks are being leveled at Nikki Haley because of the courageous stands she has taken over the years in defense of taxpayers and government reform - stands that offend many of the most powerful interests in state government," said Sanford, who endorsed Haley last November. "I am more convinced than ever that Nikki Haley is the best person to be South Carolina's next Governor."
Haley, a state Representative from Lexington, is seen as Gov. Mark Sanford's ideological heir in the governor's race, but the scandal-tainted governor has cautiously stayed out of the race to succeed him.
Lt. Gov. Andre Bauer, Rep. Gresham Barrett and Attorney General Henry McMaster are also seeking the GOP gubernatorial nomination on June 8.
McMaster was endorsed Friday by former Gov. David Beasley.
