COLUMBIA, S.C. - The airwaves are filled with the four major Republican U.S. Senate candidates touting their experience with fighting crime to creating jobs.

Candidates have spent millions of dollars on ads and each plans to spend thousands more before the primary on June 8.

Former Attorney General Charlie Condon released a 30-second ad in television markets across the state this week that focuses on domestic violence.

The ad stars Karen Petit, a domestic violence victim and women's advocate, who announces: "As attorney general, Charlie Condon increased domestic violence convictions by 41 percent."

During his eight-year tenure at the state's top prosecutor, Condon ordered prosecutors to stop dropping criminal domestic violence cases. He said it was necessary in South Carolina, which leads nationally in the rate of women who are killed by men.

Condon's second statewide ad features Charleston Police Chief Reuben Greenberg endorsement.

Former Gov. David Beasley has tapped NASCAR drivers Ward Burton, Bobby Labonte and Jeff Burton to endorse his campaign in a 60-second radio ad this weekend.

"I can think of no better way to bring people together for a good cause like our campaign than through one of our state passions - racing," Beasley says.

The ad talks about Beasley's efforts to create jobs and cut taxes in South Carolina.

Beasley also has a television ad with several South Carolina voters who claim Beasley is the most experienced candidate.

U.S. Rep. Jim DeMint doesn't even appear in his latest television ad. It features two men discussing the three-term congressman's record, his anti-abortion stance.

Thomas Ravenel is airing two 30-second television ads statewide. Ravenel talks about patriotism and his experience creating thousands of jobs through his Charleston real estate development company.
