Barrett’s body of rulings is not that large, making it difficult to extrapolate how she would rule on important issues if elevated to the supreme court. But we have ample reason to believe that Barrett, a conservative Catholic, is hostile to abortion rights and might overturn Roe v Wade when she had a chance. In addition to being a conservative Catholic, Barrett is a self-described legal “originalist” who almost certainly believes Roe was a legally shoddy opinion. (Even Ruth Bader Ginsburg was not that confident in the legal grounds for the ruling.)
The thing is, when considering constitutional law, what is being decided is whether abortion is a right. Rights stemming from the constitution and the bill of rights etc. Which is something that a judge on a constitutional court should have a view upon.
In the absence of rights as declared by said court then abortion becomes a thing of politics which is where it probably should be in my biased and unimportant view. Like it is all over Europe for example.
The very shouting about abortion rights and Roe is begging the question. Because the Roe question is whether it’s a right or not.
