And yet the majority of Americans want it repealed.

(ABC News) — President Obama tonight honed a defense of his administration’s controversial health care law, calling pledges by his Republican rivals to roll back the legislation an affront to women.

“Because of this law, preventive care is now covered and, yes, that includes preventive care for women: check-ups, mammograms, birth control,” Obama told an applauding crowd of more than 750 campaign donors in Houston.

“So when you see politicians trying to take us back to the days when this care was more expensive and harder to get for women — and I know you’re seeing some of that here in Texas — you just remember we can’t let them get away with it,” he said.

The comments on women and the health care law are a notable, new twist in Obama’s campaign stump speech. Previously, Obama has tended to focus only on provisions of the law that banned preexisting condition restrictions, allowed young adults to remain on their parents’ insurance plans and expanded prescription drug coverage for seniors.

“This is not just a political debate. This is the defining issue of our times,” Obama said later of the ideological debate with Republicans over issues like health care. “A make or break moment.”

Proceeds from both events — Obama’s 35th and 36th of the year — go to the Obama Victory Fund, a joint account of the Obama Campaign and Democratic National Committee, which funnels the first $5,000 of an individual’s contribution to the president and the remainder, up to $30,800, to the DNC.
