George Bush may have averted a midcampaign fracas over abortion. After the Supreme Court last year upheld Reagan-era regulations barring doctors in federally funded family-planning clinics from counseling patients about abortion, the White House called for new rules based on the court's decision. As a sop to pro-choice activists and doctors, the new regulations, due later this month, will permit doctors in those clinics to refer women who want to end their pregnancies to facilities that perform abortions. But in a nod to pro-lifers, nurses won't be allowed to discuss abortion. Prolifers, who lobbied hard for a gag on both doctors and nurses, say they will accept the compromise regs.
