I don't exactly know how much of national politics is optimizing for fundraising rather than for making citizens' lives better, but it's clearly far too great.
The reality is that:
1. Abortion has always been one of the most divisive topics in the US
2. Roe vs. Wade to begin with was a very shaky legal hodgepodge based around right to privacy
3. Codifying something like that takes immense political might and public approval neither of which existed in a significant capacity
60+% majorities have supported abortion as a right until near the end of the second trimester, and for the health of the mother after that (for 30+ years).
