I have been saying this for some time but people are so panicked. There is not a raiontal legal argument to tear down RvW and make abortions illegal in the country.
This is not the same as overturning Plessy v. Fergunson (separate but equal) or Dred Scott cases.
The only real fight left for the court is regulations that are too burdensome or too lenient that allow late term abortions and this, just like the 2d Amendment, is not about getting rid of it, but clarifying the permissible and impermissible regulations.
Well yeh, mostly.
Even if Roe v. Wade at its core is left alone the courts are still presented with other cases every session that deal with the spin-offs from it or abortion in general. Can you abort a fetus at 11 months, can states require mothers to go to classes to learn about adoption options before aborting, is abortion considered to be health care within the meaning of statute X,Y,Z.
Therein lies the basis for the sub silentio dance that will take place between Barrett and the dem Senators. Barrett can, probably will, or could argue that she accepts Roe v. Wade as settled law. Problem is the various interpretations of it are not settled in regard to follow-on issues. The left wants her to say that she accepts Roe as settled law and that she will not support any restrictions on abortion whatsoever. Those are two different arguments. As you said, they know the game because they are playing it themselves with the 2nd Amendment.
Not to digress but while the analogy over to the 2nd amendment is useful it is also limited. Gun rights in at least fundamental form are flat out stated as a separate constitutional amendemt. Abortion "rights?" Not so much. It is a judicially constructed argument based on an elusive "right to privacy." Which does not appear in the constitution anywhere.
