How abortion polarized America

“Here’s my question,” tweets legal scholar Jeffrey A. Sachs, obviously in response to the controversy over Supreme Court nominee Brett Kavanaugh. “What is the alternative reality where Roe was never decided, levels of partisan polarization are identical to our own, and the SCOTUS appointments process is markedly better?”

Here’s the problem with the question: If Roe v. Wade had never been decided, if the Supreme Court had just declined to hear cases challenging the constitutionality of abortion bans, levels of partisan polarization would not be anything like identical to what we see around us.
