Other women and abortion-rights groups have undertaken similar efforts. EMILY's List, for example, announced on Tuesday an effort to target women in New Hampshire as part of its WOMEN VOTE! campaign. That focuses on Congressional races in the Granite State, according to a press release.
And Planned Parenthood recently began airing ads against Romney in battleground states. The spots, worth more than $3 million, say the GOP candidate would turn back the clock on women's health.
NARAL's political action committee also is on pace to spend about $750,000 this cycle, Shipp said.
The group received an influx of cash this year after Senate candidate Rep. Todd Akin (R-Mo.) made comments about women who are victims of "legitimate" rape not needing abortions because their bodies don't allow a pregnancy to occur. Akin later apologized.
Musgrave said her side is energized, too, and is drawing on the polling of anti-
abortion organizations showing that most women think there should be a ban on abortions based on what the gender of the child will be and those done late in a pregnancy.
"I live in Colorado, and this last election after candidate Obama said he wanted to find common ground on the issue, I'd be driving down I-25 and see a pro-life sticker and an Obama sticker on the same car," Musgrave said. "We are doing everything we can to make sure they know this president did anything but find common ground on the issue."
