It never really was about abortion. It was always about building power for conservative christian institutions. Abortion was just the issue that they were able to build a power base around -- particularly by uniting Catholics and Evangelicals who previously didn't really get along. It was mostly an invented controversy that sprang up in the wake of Roe as part of a larger de-liberalization movement.
Even today, the statistics of people who actually believe that abortion should be fully and unconditionally banned -- what the conservatives are all legislating for -- is only something like 8%. Another 29% think there are at least some exceptions, and a vast majority think it should be mostly or completely legal.
In the numbers, this is a settled issue. It isn't even THAT contentious.
But the issue is politically incredibly useful, and the religiously fundamentalist institutions do a great job having outsized influence and concentrating power. It's a rare opportunity for conservatives to take a pseudo-ethical stance and advocate for an actual outcome -- normally they just look like weird, selfish freaks shouting "no no no" all the time. The fact that the ethics aren't there is irrelevant.
