On both sides of America’s abortion debate, activists are convinced that the 1973 Supreme Court ruling establishing a nationwide right to abortion is imperiled as never before. Yet no matter how the current conservative-dominated court handles pending high-profile abortion cases, there will be no monolithic, nationwide change. Instead, the fractious state-by-state battle over abortion access will continue. The demise of Roe v. Wade would return abortion policymaking to the states. At least 20 Republican-governed states would likely impose sweeping bans; perhaps 15 Democratic-governed states would reaffirm their strong support for abortion access.
