But that hadn't been the law since 1992

Casey ditched the trimester regimen.

This is the problem with trying to gauge public perception of these issues. People use phrases and don't know what they mean. We use "Roe" as a proxy for "Roe and it's progeny," even though the contours of Roe's rule weren't maintained by its progeny.

And as for the any-reason-up-to-birth, it's precisely that. That's what Doe and Casey permitted, because their jurisprudence didn't allow for practical enforcement of the restrictions they purported to permit. Gonzales v. Carhart allowed a restriction in the form of the Partial Birth Abortion Ban Act, but that only applies to one form of procedure.
