MACON, Ga. -- Add Michelle Nunn to the growing list of Democrats who support a temporary travel ban from West Africa to the United States in order to control the spread of Ebola.

"I support a temporary travel ban with the exceptions of our medical and military personnel in those affected areas in West Africa and I believe that we need to look to our medical practitioners, leaders and scientists and make sure we’re giving them the resources," Nunn said Friday in an interview with The Washington Post.

She also called on President Obama and lawmakers to work together "to make sure that we’re protecting our citizenry first and foremost and keeping them informed. And alleviating panic and anxiety."

Nunn is one of several mostly moderate Democrats who have joined with a much larger group of Republican lawmakers in calling on the U.S. government to temporarily prevent people departing from African countries afflicted by the disease from entering the United States. On Friday, Sen. Kay Hagan (D-N.C.) -- who is locked in a tight reelection race -- and rising party star Rep. Tulsi Gabbard (D-Hawaii) also joined the list of those supporting a ban.

In Georgia, Nunn has edged ahead of Perdue in two polls released this week, scrambling a race that wasn't expected to be this competitive or closely-watched in the final days of the campaign. In response, national Democrats and Republicans are pouring millions of dollars into the state to bankroll a new wave of TV ads, while an anti-Nunn super PAC has also bolstered its spending.

In recent weeks, Nunn has unleashed a series of her own TV ads citing news reports that raise questions about parts of Perdue's 40-year business career. Most of the attention focuses on work he did to help a North Carolina textile firm that shuttered after he left to revive the retailer Dollar General. Perdue is touting his work with the discount retailer, noting that he helped the company create 20,000 jobs and expand to 35 states. He has staunchly defended the arc of his career, and his decision in some instances to outsource jobs or company services.

During an exchange with reporters on Wednesday, Perdue suggested that his critics "really don’t understand, you know, what it takes to create jobs and create economic value — which is really what this free enterprise system is based on."

Nunn responded to Perdue's charge Friday: "He said that we don't understand the American enterprise system. But I think that we do understand the American enterprise system, we're just not sure that that qualifies you to be the United States senator from Georgia."

Republicans in recent days have noted that Nunn declined to tell a GOP operative who follows and videotapes most of her public appearances whether she voted for Obama in 2008 and 2012.

Nunn put those doubts to rest in the interview.

"I did vote for the president. I have said throughout the campaign that we need more people in Washington working with the president – Republican or Democrat – to get things done. I pledge to do that on behalf of Georgians," she said.
