I'll go out on a limb here, and suggest Trump may not share your view.
Just guessing, because my Trump speak isn't fluent. He probably goes with a states rights angle.
Ultimately, I’m okay with a state’s rights angle, if every state bans all abortions in all cases.
But that’s not where we are. So even though I’m a purist, I don’t mind gobbling up enemy territory along the way.
First, we need a way around Roe, I would prefer if the Court would simply reverse itself. A Human Life Amendment would be difficult, but in some ways, preferable. Placed in the Constitution it would be beyond the reach of the back-robed tyrants or Congress or the Executive.
If strictly-enforced,I could be persuaded to accept the Great Exception cases, as I call them, in the short-rerm.
I’d like to hear some specifics from trump, otherwise his attacks on Carson are scurriilous.
