You're right and wrong. Changes plenty. Now states don't have to make abortion legal through 3 months if they don't want to. Most states still allow abortion, too, but many that do only allow it through a certain gestational time, like up to 8 weeks ir what have you. Many states will continue allowing it abortion up to birth…. now, what Biden said about codifying abortion federally? If such a thing happened - and this is why the midterms are theoretically so important - it could or would effectively make the SCOTUS ruling moot.
