Even some liberal Constitutional proponents agree Roe vs. Wade is bad law and have called for it to be overturned based on overreach.
This argument is a strong one and is easily explained to idiotic liberals who believe abortion rights are a virtue.
The Court found that there is a Constitutionally protected right to privacy. To merely "overturn" Roe the Court would have to find that this is not true. This the Court will never do. The court will have to find that, regardless of the Constitutionally protected right to privacy, other rights have preeminence. This is how judicial decisions are made that disagree with previous decisions. There will be no decision that states that the Blackmun Court "overreached it's bounds". There will be no decision that states that the abortion issue is to be determined only by the states. Supreme Court decisions are not written like that. A decision might be made that alters the findings in Roe, but it will be based on Constitutionally protected rights, as Roe was, not on states rights.
