"Why did the abortion debate escalate and become the defining site of political division in the nation? The history of the abortion conflict in the period before Roe raises a variety of questions about Court-centric explanations for Roe rage—and accordingly suggests the need for historical inquiry into the sources of the polarization so often attributed to the decision. While the history of conflict over abortion before Roe cannot tell us what happened after the Court ruled, it can and does raise powerful questions about the logic of polarization in the decades after Roe precisely because it demonstrates how the abortion conflict could accelerate and become entangled in party politics in a period when the abortion conflict cannot be plausibly construed as a response to judicial review. The history of the pre-Roe period thus illustrates the need for a deep history of the post-Roe period if we are to make any reliable judgments about how and why Roe came to be the site of polarizing and identitarian conflict that it now is."
