Most Americans don't like abortion laws the don't take into account the health of the mother. So that type of law becomes a wedge among Republicans.
Conversely, if a state passes a six week ban (Florida), that's going to draw out these distinctions among Democrats.
I'm not making a moral claim. I'm commenting on the politics of campaigning on it. I think politicians are advantaged at avoiding wedge issues and focusing on material concerns that affect the most people.
Texas's law allegedly takes into account the life of the mother. And yet mothers are dying because of this law. When you make it that the OB office needs to have the legal team on speed dial to make sure they're not facing life in prison on a regular life or death healthcare your law is abhorrent policy.
The politics of campaigning on it is to make people think only unplanned pregnancies are affected by these laws. I am making a moral claim on that; it's reprehensible.
