Mitt Romney's campaign has a released a new television ad featuring a woman who backs the GOP nominee after voting for President Obama in 2008.

The 30-second spot comes as new polls show Romney making gains in swing states after his much-applauded debate performance on Wednesday night.

But the former governor still lags behind Obama with women voters, polls have found.

The new ad shows a small-business owner, Melanie McNamara, speaking with remorse about her vote for Obama.

"I'm disappointed in Barack ObamaBarack Hussein ObamaTrump adds to legal team after attacks on Mueller Stock market is in an election year: Will your vote impact your money? Trump will perpetuate bailouts by signing bank reform bill MORE as my president because he promised … that we're all going to be able to prosper," McNamara tells the camera. "I don't see the prospering."

The ad makes a bid for women voters by arguing that Romney will be better for the economy – an issue women care about, McNamara says, because "you think about your children."

In a slide of text, the ad states that "there are over 450,000 more unemployed women" since Obama took office, according to the Bureau of Labor Statistics.

"What I want to think about is a future that has jobs, where our economy is growing again. That's important to women, and it's important to me," McNamara says.

McNamara is from North Carolina, a crucial swing-state, and this is not the first time her support for Romney has put her in the spotlight.
