Obama ad courts women

CNN Producer Gabriella Schwarz

(CNN) – President Barack Obama's re-election campaign on Thursday released the first in a series of television ads targeting female voters.

The 30-second spot points to the Lilly Ledbetter Fair Pay Act, the first law signed by the president that makes it easier for women to receive the same compensation as men doing the same work.

"The son of a single Mom, proud father of two daughters, President Obama knows that women being paid 77 cents on the dollar for doing the same work as men isn't just unfair, it hurts families," the narrator in the spot says.

The commercial, "First Law," will run in the battleground states of Colorado, Florida, Iowa, North Carolina, Nevada, Ohio and Virginia, according to the campaign. They described the ad buy as "significant."

Although Mitt Romney, the presumptive Republican presidential candidate, has said he will not seek to overturn the Ledbetter law if elected, he has not said whether he would have signed the bill.

Obama has consistently edged out his GOP rival in polling of registered female voters, a demographic he captured with 56% support in 2008, but the gap has narrowed recently.
