"If Roe conformed to then-dominant modes of reasoning about abortion, at a time when the Gallup poll reported the belief of two-thirds of Americans that the abortion decision should be left to a woman and her doctor, how are we to understand the outcry against the decision that steadily mounted over the 1970s? Our review of the debate before Roe reveals several factors contributing to the conflict over abortion that were in play well before the Court issued its decision in January 1973, and identifies still other developments that intensified the conflict much later in the decade."
