(CNN) - Sarah Palin has recorded an automated phone call urging Republicans in South Carolina to vote for Nikki Haley, her chosen candidate in next Tuesday's GOP gubernatorial primary.
The former Alaska governor endorsed Haley last month, is featured in one of her television ads and has been one of Haley's staunchest defenders in the wake of two separate allegations of infidelity that have roiled the governor's race.
In the robocall launched Thursday, Palin tells voters she is "calling on behalf of my good friend, and a brave and strong conservative woman, Nikki Haley."
Palin says that Haley's rivals are attacking her with "made-up nonsense to try to knock you down."
"Believe me, I've been there," Palin says in the recording. "But you can make your own statement against these unfair attacks, and you can help take back state government, by voting for the real deal conservative, Nikki Haley on Tuesday."
Haley's campaign manager Tim Pearson said in a statement that "few people know better than Sarah Palin what it means for a conservative reformer to take on the establishment – and the blowback that comes with it."
During the 2008 presidential campaign, Palin criticized the practice of dialing voters with recorded campaign messages, saying that voters get "irritated" by such calls. But she has since recorded phone messages for other Republican candidates.
Haley's opponents in the primary are Lt. Gov. Andre Bauer, Attorney General Henry McMaster and Rep. Gresham Barrett. Unless one of the candidates earns more than 50 percent of the vote next Tuesday – an unlikely prospect – the race will head to a runoff between to the top two finishers.
