Vice President Biden hit the Republican presidential ticket over women’s issues at a rally in Fort Pierce, Florida, on Saturday, as the Obama campaign looked to shore up its eroded support among the core constituency.

“What do you think are the chances of Roe v. Wade surviving a Romney Supreme Court?,” Biden asked.

“They don’t believe a woman has a right to control her body,” he continued. “On women’s healthcare, they want to turn the power back over to the insurance companies.”

Biden said Republicans viewed pregnancy as “a pre-existing condition.”

The Obama campaign has accused Romney of trying to “cloud” his views on women’s issues. Romney has said he would be a “pro-life president,” but that he wouldn’t pursue specific legislation aimed at outlawing abortion.

Biden on Saturday also reprised a moment from Tuesday’s presidential debate over the Lilly Ledbetter Equal Pay Act, the first legislation Obama signed into law upon taking the White House.

“On Tuesday when Romney was asked a question about women’s equal pay, he started talking about binders,” Biden sad. “He never did answer the question by the way.”

The Internet was abuzz over a moment in the debate in which Romney referred to "binders full of women.” Romney was explaining that as governor, he intentionally sought female candidates for top-level posts.

“And I said, ‘Well, gosh, can’t we — can’t we find some, some women that are also qualified?'” Romney said. “I went to a number of women’s groups and said, ‘Can you help us find folks,’ and they brought us whole binders full of women.”

Social media quickly flooded with jokes about the inadvertent remark, with a Tumblr page and Twitter handle poking fun at the comment earning tens of thousands of shares.

The Romney campaign sought to capitalize on the story by highlighting Romney’s female Cabinet member appointments during his tenure as governor of Massachusetts.

But earlier this month, a poll from the Pew Research Center found Obama leading by a mere 3 points among women. That finding was all the more striking because the same organization had found Obama holding an 18-point edge the previous month.

The reversal in the president’s fortunes is almost certainly traceable to his widely panned performance in the first presidential debate last week.
