NARAL Pro-Choice America's political action committee has decided to drop its neutral stance in the Democratic primary — in large part to send a signal that it's ready to get behind the candidate board members view as the likely nominee, according to the group's political director, Elizabeth Shipp.

"A political organization always looks at viability — who has the most delegates, the most votes, and the most cash on hand," Shipp told ABC News. "As a political organization, we're not going to say it's an easy decision, but it's the right one."

Just talked to a 55-year-old Columbus, Ohio resident named Cynthia Ruccia, a spokesperson and organizer for a group calling itself "Clinton Supporters Count Too." She said the group — numbering in the hundreds, and organized in Ohio, Pennsylvania, Florida, and Michigan — stands ready to boycott the Democratic Party if Clinton doesn't win the nomination, and will work against superdelegates who support Obama over Clinton as a means of registering their displeasure with the party.

"We have a plan to campaign against the Democratic nominee," the group said in a press release Thursday. "We have the (wo)manpower and the money to make our threat real. And there are millions of supporters who will back us up in the swing states. If you don’t listen to our voice now, you will hear from us later."

Ruccia tells ABC News that she believes "millions" of women share her group's views, though they have only begun to make contact with like-minded women. They're disgusted, she said, that Democratic Party leaders haven't more aggressively denounced sexist media comments and coverage in the campaign, and are angry at the drumbeat for Clinton to get out of the race.

"We're just at the boiling point," Ruccia said. "Women will sit back and be quiet about things for a while, but we've had enough. Unless Hillary Clinton is our nominee, we are not going to support the nominee."

But in gauging the fallout among female voters of this divisive campaign, it's also worth keeping in mind what's going on in the wake of NARAL Pro-Choice America's decision to endorse Obama on Wednesday.

As documented by the Huffington Post's Sam Stein, NARAL blogs are being overwhelmed, and many state affiliates are angry at the national group's decision.

Emily's List is furious. And Martha Burke, former chair of the National Council of Women's Organizations, tells Stein she is "disappointed": "It feels like they are abandoning a known ally for a less committed candidate because they want to jump on a bandwagon. I think the pro-choice community should stick by a woman who has stuck by them."
