Throughout the health care debate, Democrats and President Obama have insisted that Americans who want to maintain their current health care coverage will be able do so. Reform, Democrats argued, would be a win-win, extending coverage to millions of uninsured Americans while depriving nobody of existing coverage they like.

But events this month have forced liberals to admit an inconvenient truth: Not only will health care reform force millions of Americans to change health insurance plans against their will, but those shifts could also cause millions of women to lose coverage for abortion.
