(CNN) - Sen. Lindsey Graham of South Carolina, who's up for election to a third term next year, talked about his conservative credentials Sunday, one day after he got another challenger from the right in the 2014 Republican primary for his seat.
"I will continue to be Lindsey Graham, a solid fiscal and social conservative who wants to solve problems. I think that's the future of the Republican Party," he said on CNN's "State of the Union."
Nancy Mace, a resident of Charleston who runs a public relations firm and was The Citadel's first female graduate from its Corps of Cadets in 1999, announced Saturday she would challenge Graham for his Senate seat.
"There are powerful forces in Washington that consider individual liberty passé and the Constitution dead letter. I believe our state desperately needs new leadership," she said in a prepared statement.
Former congressional candidate Richard Cash, who has a solid following among social conservatives, is also running in the Republican primary.
But Graham will probably be considered the front-runner, with his strong name recognition and a sizable war chest of $6.3 million as of June 30, according to Federal Election Commission reports. In 2008, Graham won his seat in the general election with 58% of the vote.
"I'm going to keep being a social and fiscal conservative that focuses on our national security, takes care of interests at home, like the Port of Charleston, working with my state officials, and be a conservative like Ronald Reagan who will sit down with a Tip O'Neill to solve Americans' problems," Graham told Candy Crowley, CNN's chief political correspondent.
