WASHINGTON, D.C., October 30, 2012, ( – President Barack Obama has released his fifth campaign commercial attacking Mitt Romney on the issue of abortion.

The new ad, entitled “What He’ll Do,” compiles a montage of instances when Romney said that he would like to see the Supreme Court overturn Roe v. Wade, the 1973 decision that struck down many states’ prohibitions on abortion.

It also highlights his pledge to end federal funding for Planned Parenthood.

“No matter what Mitt Romney’s ads say, we know what he’ll do,” the female narrator says. 

As the economy continues to sputter, and with his signature policy accomplishment ObamaCare deeply unpopular, the president has turned to abortion as a wedge issue to increase the turnout of single female voters, a heavily Democratic constituency

NARAL Pro-Choice America President Nancy Keenan says she has identified five million “Obama defectors” – women who voted for the president in 2008 but have changed their minds. Three million are in swing states. 

“We have gone into battleground states and counties that are going to make the difference – by literally 1 percent, or a half-percentage point,” Keenan said.

Part of the strategy has been to dispatch Sandra Fluke as a surrogate. The San Francisco Chronicle reported that Fluke spoke to a standing room only crowd at a NARAL fundraiser in California. However, neither California nor NARAL voters are being contested. At a rally in the swing state of Nevada, Fluke drew a crowd of 10.

The Romney campaign has deflected charges that the ticket is too pro-life with a campaign ad declaring “abortion should be an option” in instances of rape and incest. 

On Monday, former U.S. Senator and top Romney surrogate Norm Coleman, R-MN, told a Republican Jewish Coalition meeting in the affluent Cleveland suburb of Beechwood that Roe v. Wade is “not going to be reversed” during the Romney administration.

“President Bush was president eight years; Roe v. Wade wasn’t reversed,” he said. “He had two Supreme Court picks; Roe v. Wade wasn’t reversed.”

The next president is expected to name a successor to Justice Ruth Bader Ginsburg, a fervent supporter of abortion-on-demand.
