“Legislation legalizing Abortion” would now be Un-Constitutional, on its face, wouldn’t ? (Not that Constitutionality has ever been a concern of Progressives)
No...if a federal law regulating abortions and allowing them across all 50 states went into effect it would not necessaritly be against the constitution. It simply takes the federal court systems out of the abortion morality business and lays the blood of murdered children more directly at the feet of the congress and the senate and the people that elected them!
