This is only tangentially related, bu Roe was decided with the idea of State’s rights in mind (which is why the Supreme Court left much of the actual administering of Roe to States). FOCA, on the other hand, unifies all states under one regime. A major tread on State’s rights. While FOCA does roll back everything, all of this only works if the Supreme Court still interprets abortion as being a constitutional right (filed under “privacy”). If that changes, then all bets are off. Abortion regulation falls back to the states. FOCA becomes unconstitutional and the only way the Federal gov’t can regulate abortion is through the Commerce Clause.
