Dan Blue, Erskine Bowles, Cynthia Brown and Elaine Marshall participated in a lively debate, discussing their visions for the state's future.
Law students and audience members questioned the candidates on issues ranging from nuclear power to gay rights.
Marshall, the N.C. secretary of state, said a desire to change many aspects of society caused her to pursue a career in politics in an effort to help others.
"I've been on the side of people my entire life," she said.
Marshall said that after her 1996 win over legendary NASCAR driver Richard Petty in the race for secretary of state, she is ready to confront Elizabeth Dole, who is expected to win the Republican nomination for the Senate seat. "Indeed, I wasn't afraid of King Richard, and I'm not afraid of Queen Elizabeth," she said.
Marshall said she is concerned with the growing income disparity between urban and rural regions and wants to continue fighting for farmers and workers. "We need an economic policy that creates jobs for regular people," she said.
Marshall added that the United States should continue to aid feuding countries in the Middle East. "The United States must play an effective and constructive role in the Mideast."
Brown, a former Durham City Council member, said she will focus on assisting the state's workers.
"Public policy must serve -- first and foremost -- the needs of working people," she said.
