I hope you’re just theorizing. We rightfully griped for fifty years about the fact that Roe was a usurpation of states’ police powers, I.e., not a federal issue. That’s the notion on which Dobbs v Jackson women’s Health Organization is founded. To now come up with some Jerry-rigged theory to make it a federal issue would be the height of hypocrisy. No such statue would get past the Senate in any event
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.
