A new ad from President Obama's campaign paints Mitt Romney as unsympathetic to the middle class-this time, to mothers in particular.

The ad claims middle-class moms could get squeezed by Mitt Romney's economic policies, and it will air in six battleground states, according to a campaign official: Colorado, Iowa, New Hampshire, Nevada, Ohio and Virginia. It already aired in one media market-Denver, Colo.-shortly before 5 a.m., according to trackers at Kantar Media's Campaign Media Analysis Group. Obama's campaign has yet to unveil the ad publicly.

In it, a woman named Cindy tells viewers, "I do the laundry, I pay the bills, I make sure my kids are fed and rested and healthy."

A narrator breaks in: "Moms like Christie would be stretched even more under Mitt Romney. To fund his tax cuts for millionaires, Romney could take away deductions for child care, home mortgages, and college tuition," citing analysis from the Tax Policy Center, which deduced that Romney would have to cut benefits and raise taxes in order to maintain his simultaneous promises of deficit reduction and maintaining Bush-era tax rates on high incomes.

Christie concludes: "Mitt Romney-he's so focused on big business and tax cuts for the wealthy. It seems like his answers to middle-class America are just, 'Tough luck.'"

As ABC's Amy Walter wrote in today's edition of The Note, Obama has succeeded in swaying women away from Romney:

The "war on women" has been a mantra from Team Obama for months now. And, a focus group of northern Virginia voters shows that it has penetrated. Three undecided women voters, including Ann, a 2008 McCain voter, said that Romney's views on women's issues worried them. Mary, an '08 Obama voter, said she likes Romney's business background but "Obama will be better on women's health and that makes a difference to me."

The ad also uses a hobbyhorse for the Obama campaign: analysis by the Tax Policy Center, a joint endeavor of the Urban Institute and the Brookings Institution, which examined Romney's economic plan and concluded that he would have to raise classes on middle-class incomes to keep his promises while enacting other parts of his plan. The Romney campaign has criticized that analysis, while the Obama campaign has made it the centerpiece of its recent attacks on Romney's economic agenda.
