That's exactly what southern states said pre-1860. They were wrong and so are you. Abortion is the top issue for 1 out of every 8 Americans. And probably one of the top 3 issues for over half Americans.
This was, is and will always be a prominent national issue. Punting it down to the states is a cop out.
It’s quite naturally already in the states, right now. No punting took place.
