Non of the pro-abortion camp believes that the anti-abortion camp won’t now pursue federal restrictions.
Congress and the Supreme Court generally have figured out how to federalize almost any regulation or law that they want. Enumerated powers is a very weak reed on which to rely.
And the most extreme position against abortion is to have the Supreme Court decree that life begins at conception and that the fetus has all the legal protections of a baby already born.
The abortion issue is a very potent political issue at the national level, particularly since there are now a lot of activated single-issue pro-abortion voters.
So we return to constitutionalism by ignoring the Constitution like they do?
